The pith
A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.
The reading
What carries the argument
The engine of the positive results is a monomial-counting identity for elementary symmetric polynomials: modulo the Boolean axioms, $e_{d,n}(x)e_{k,n}(x) = 2^{d+k}e_{d+k,n}(x)$ plus lower-degree terms whenever $k \le n-d$. Iterating this identity shows that any symmetric polynomial of degree $d$ can only be multiplied into 1 by a polynomial of degree at least $n-d+1$; a similar exact coefficient analysis of the degree-2n slice of the reciprocal of the invariant polynomial $Q(x,y)=\prod_{i\ \text{odd}}(x_i y_{i+1}-y_i x_{i+1})-\beta$ gives the invariant degree lower bound. These degree bounds are lifted to size bounds by substitutions such as $w_{i,j}\mapsto z_{i,j}x_i x_j$, which embed the original hard instance into a larger one so that evaluation dimension, the dimension of the space of partial Boolean evaluations, is large, forcing large roABP width. The barrier is carried by the identity $1-\prod_i(1-f_i(x))$, the arithmetic AND of Boolean polynomials, which is 1 on the Boolean cube and hence derivable from Boolean axioms; a sufficiently strong proof system derives this AND efficiently, so any hard $f$ that implies the Boolean instance $F$ yields a small circuit computing $1/f$.
What would settle it
Take a specific unsatisfiable CNF $F=\{f_i=0\}$, a polynomial $f$ with no Boolean roots that semantically implies $F$, and a proof system $P$ claimed to be sufficiently strong. If one can exhibit a sequence of instances where either deriving the arithmetization of $\bigwedge_i f_i$ from $F$ or deriving each $f_i$ from $f=0$ provably requires superpolynomial size, while $1/f$ still has no small circuit in the relevant class, then the barrier theorem's premise fails for that system.
Extended reading notes
Core claim
The paper establishes two complementary statements. Positively, it shows that Nullstellensatz degree lower bounds can be obtained and then lifted to IPS size lower bounds for two families of non-Boolean hard instances: every unsatisfiable symmetric polynomial of degree $d$ requires refutation degree at least $n+1$, and an invariant polynomial $Q(x,y)$ built from $n$ determinants requires degree $2n$; lifting these with gadget substitutions gives exponential roABP-IPSLIN\' lower bounds and quasipolynomial multilinear-formula-IPS lower bounds, including the first finite-field results for such fragments. Negatively, the functional lower bound method is shown to be powerless for Boolean instances against sufficiently strong proof systems: if a proof system can efficiently derive the arithmetization of the AND of any Boolean polynomials, then any Boolean instance $F$ is refutable from Boolean axioms once a single hard polynomial $f$ implies $F$, so no lower bound against $F$ can follow from hardness of $1/f$.
Load-bearing premise
The barrier applies only to proof systems that can efficiently derive the arithmetization of the conjunction of any Boolean polynomials; if a system lacks this AND-introduction power, the construction that produces a small circuit for $1/f$ collapses.
Editorial extensions
If this is right
- Every unsatisfiable symmetric polynomial of degree $O(\log n)$ can be lifted to an instance with $2^{\Omega(n)}$ lower bound against roABP-IPSLIN\' in any variable order.
- The invariant instance gives the first IPS fragment lower bounds over finite fields: $\exp(\Omega(n))$ for roABP-IPSLIN\' and $n^{\Omega(\log n)}$ for multilinear-formula-IPS.
- Constant-depth IPS lower bounds now hold for refutations of individual degree $O(\log\log n)$, a strictly stronger model than multilinear constant-depth proofs.
- The functional lower bound method cannot prove lower bounds for Boolean instances against $\mathrm{AC}^0[p]$-Frege, $\mathrm{TC}^0$-Frege, or constant-depth IPSLIN\' with Boolean instances, because those systems have AND-introduction.
- The open route left is CNF lower bounds against roABP-IPS and multilinear-formula-IPS, which are not sufficiently strong in the barrier sense.
Reading between the lines
- Beyond the paper, the barrier suggests that any candidate for Boolean lower bounds via algebraic proofs must either use a proof system that cannot efficiently derive conjunctions, or use a method other than the single-function $1/f$ reduction.
- The exact degree-2n coefficient characterization of the invariant instance points to a family of functional-lower-bound hard functions parameterized by group actions; other vector invariants with sparse high-degree slices may yield further finite-field hard instances.
- The tradeoff between depth and individual degree in the constant-depth theorem offers a concrete next test: whether constant-depth refutations of individual degree $\omega(\log\log n)$ can be ruled out for stronger Boolean-like instances, or whether the upper bounds for pigeonhole and Tseitin formulas can be pushed to higher individual degree.

Referee Report
Summary. The paper develops lower bounds for fragments of the Ideal Proof System (IPS) via the functional lower bound method. It claims Nullstellensatz degree lower bounds for symmetric and vector-invariant polynomial instances, lifts these to size lower bounds against roABP-IPSLIN' and multilinear-formula-IPS refutations (including the first IPS-fragment lower bounds over finite fields), proves constant-depth IPS lower bounds for refutations of bounded individual degree, and establishes a barrier theorem showing that the functional lower bound method cannot yield lower bounds for Boolean instances against sufficiently strong proof systems such as AC0[p]-Frege and TC0-Frege. The paper positions these results as extending FSTW21 and GHT22 and as resolving a question from AGK+23.
Significance. If correct, the results are significant: they give new hard instances beyond subset-sum variants, the first IPS fragment lower bounds over finite fields, a strengthened constant-depth lower bound, and a clean limitation result for the functional method. The vector-invariant results in Sections 3.2 and 5 and the barrier argument in Section 7 are largely self-contained and the barrier theorem is elegant. However, two load-bearing technical statements are false as written: Claim 26 in Section 3.1 and Lemma 48 in Section 6.1.1. The latter in particular invalidates the claimed constant-depth lower bounds of Theorem 44. The results are likely repairable, but the manuscript requires substantial revision before the advertised theorems can be accepted.
major comments (2)
- [§3.1, Claim 26 and Eq. (26.1)] Claim 26 is false as stated. For example, with n=3, d=1, k=1, we have e1,3(x)·e1,3(x) = e1,3(x) + 2e2,3(x) modulo x^2−x, whereas the claim asserts 4e2,3(x) plus lower-degree terms. The error is in Eq. (26.1): for a fixed (d+k)-subset c, the number of ordered disjoint pairs (a,b) with a∪b=c and |a|=d, |b|=k is the binomial coefficient C(d+k,d), not 2^{d+k}. Because Lemma 25 and Corollary 27 identify the leading elementary-symmetric term using this coefficient, the proof of the symmetric Nullstellensatz degree lower bound is invalid as written. Replacing 2^{d+k} by C(d+k,d) appears to preserve the intended conclusion (the coefficient is nonzero when the characteristic exceeds d+k), but the argument must be explicitly corrected.
- [§6.1.1, Lemma 48] Lemma 48 is false as stated, and the constant-depth bounded-individual-degree lower bounds built on it are therefore unproven. Counterexample: let t=2, Q1=x1^2, Q2=x2^2, d=2, δ=2, and k=1. Then d'=4 and residue_1(2,2)=1/2, so the condition in the RHS is k0 + (k/(d−k))ℓ0 = k0+ℓ0 ≤ 3/4. The only nonnegative integer pair is k0=ℓ0=0, so the RHS is span{1, x1^2, x2^2, x1^2x2^2}, which does not contain ∂_{x1}(Q1Q2)=2x1x2^2. The proof sketch also contains an incorrect algebraic identity: |κ_i| − (k/(d−k))(d'_i−|κ_i|) equals (d/(d−k))|κ_i| − kd'_i/(d−k), not (δd/(d−k))(|κ_i| − (k/(δd))d'_i) unless δ=1. Since Corollary 49, Lemma 53, Lemma 59, and Theorem 44 all rely on Lemma 48, Theorem 44 and the claimed strengthening of GHT22 are not established by the present manuscript.
minor comments (3)
- [§6.1.1, Corollary 49] The maximization condition in Corollary 49 writes residue_k(d1,...,dt)/δ, but the lemma concerns degrees d'_1,...,d'_t; it should read residue_k(d'_1,...,d'_t)/δ for consistency with Lemma 48.
- [§6.1.2, Lemma 51 proof sketch] The displayed formula for α contains a typo: '∑_{ν=0}^{Δ−1} (−1)^nu τ^{2ν−1}' should presumably be '∑_{ν=0}^{Δ−1} (−1)^ν τ^{2^ν−1}'.
- [§4.1.2, Proposition 37 and Corollary 38] The statements say m=(n choose 2), but the lift in Eq. (35.3) is defined with m=(2n choose 2) and w={w_{i,j}}_{i<j∈[2n]}. The bound char(F) > max(24n+2m, nd) and the number of z-variables should be checked against the correct value of m.
Circularity Check
No circular reduction found: the main lower bounds and barrier are proved in-text from explicit computations and published external machinery, and the flagged Lemma 48 gap is a correctness issue, not a circular one.
full rationale
The paper's derivation chain is self-contained rather than circular. The degree bounds (Theorem 32) rest on an explicit coefficient computation (Lemma 30), the size bounds (Theorem 41) are proved via coefficient-dimension arguments on the gadget instance P(u,z) constructed in the paper, and the barrier (Theorem 65) is proved from Definition 64 by a genuine collapse: equations (65.1)-(65.3) exhibit sum_i h_i g_i in C' computing 1/f over the Boolean cube. The definition of 'sufficiently strong' states the AND-introduction hypothesis; it does not assert the conclusion, and the paper explicitly records the escape route (roABP-IPS and multilinear-formula-IPS are not sufficiently strong; CNF lower bounds there remain open, Section 7.1), so no result is equal to its own input by construction. No parameter is fitted and then renamed a prediction; beta is a free constant chosen only for unsatifiability. Self-citations (FSTW21's Theorem 1, GHT22's Claim 58, LST21) point to published peer-reviewed results used as tools; FSTW21 is restated with its proof sketched in-text, and GHT22's Claim 58 is parameter-free and does not encode the target lower bound, so these citations are real evidence under the review rules, not load-bearing circularity. One non-circularity issue is flagged for the record: Lemma 48 (Section 6.1.1) is false as stated. Take t=2, Q_1=x_1^2, Q_2=x_2^2, d'=4, d=2, delta=2, k=1; then residue_1(2,2)=1/2 and the index condition k0+(k/(d-k))·ell0 <= k - residue/delta = 3/4 forces k0=ell0=0, so the right-hand side is span{1, x_1^2, x_2^2, x_1^2·x_2^2}, which does not contain partial_{x_1}(Q_1·Q_2)=2·x_1·x_2^2. The proof sketch's identity sum_i (|kappa_i| - (k/(d-k))·(d'_i - |kappa_i|)) = sum_i (delta·d/(d-k))·(|kappa_i| - (k/(delta·d))·d'_i) holds only for delta=1. Corollary 49, Lemmas 53 and 59, and Theorem 44 depend on Lemma 48, so the bounded-individual-degree constant-depth bounds are unproven as written. This is a correctness gap, not a circular reduction; the overall verdict is no significant circularity.

Strong algebraic proof systems such as IPS (Ideal Proof System; Grochow-Pitassi [GP18]) offer a general model for deriving polynomials in an ideal and refuting unsatisfiable propositional formulas, subsuming most standard propositional proof systems. A major approach for lower bounding the size of IPS refutations is the Functional Lower Bound Method (Forbes, Shpilka, Tzameret and Wigderson [FSTW21]), which reduces the hardness of refuting a polynomial equation f(x) = 0 with no Boolean solutions to the hardness of computing the function 1/f(x) over the Boolean cube with an algebraic circuit. Using symmetry, we provide a general way to obtain many new hard instances against fragments of IPS via the functional lower bound method. This includes hardness over finite fields and hard instances different from Subset Sum variants, both of which were unknown before, and stronger constant-depth lower bounds. Conversely, we expose the limitation of this method by showing it cannot lead to proof complexity lower bounds for any hard Boolean instance (e.g., CNFs) for any sufficiently strong proof systems.
