abstract

We prove that if there exists a $C$-subsolution to a constant coefficients strictly $\Upsilon$-stable general inverse $\sigma_k$ equation, then there exists a unique solution. As a consequence, this result covers all the analytical results of the classical strictly $\Upsilon$-stable general inverse $\sigma_k$ equations, for example, the complex Monge--Amp\`ere equation, the complex Hessian equation, the J-equation, the deformed Hermitian--Yang--Mills equation, etc. Hence, we confirm an analytical conjecture by Collins--Jacob--Yau [arXiv:1508.01934] of the solvability of the deformed Hermitian--Yang--Mills equation. Their conjecture states that the existence of a $C$-subsolution to a supercritical phase deformed Hermitian--Yang--Mills equation gives the solvability.

  1. The Critical LYZ Equation in K\"ahler Geometry

    math.DG 2025-11 conditional novelty 8.0 of 10

    The critical phase of the LYZ/dHYM equation on compact Kähler manifolds is solvable under the expected subsolution condition, resolving an open problem posed by Collins–Jacob–Yau and Li.

  2. A numerical criterion for complex Hessian type equations on projective manifolds

    math.DG 2026-08 conditional novelty 7.0 of 10

    Existence of solutions to complex Hessian-type equations on projective manifolds is equivalent to uniform positivity of certain subvariety integrals when the associated polynomial is strictly right-Noetherian.

  3. Ideal G{\aa}rding polynomials

    math.CO 2026-07 conditional novelty 7.0 of 10

    Ideal Gårding polynomials — a convexity-enhanced subclass of Gårding polynomials — are characterized by concavity and Lorentzian conditions, and univariate members are modeled by Pitman–Stanley polytope volumes.
