  1. Cluster structures on $SL_n/SO_n$

    math.RT 2026-07 conditional novelty 7.0 of 10

    SL_n/SO_n, its strata ˚S_w, and the symmetric matrices Sym_n admit cluster algebra structures, obtained by folding the cluster structure on SL_n.

  2. Electrical networks, Grassmannians, and cluster algebras

    math.CO 2026-07 accept novelty 7.0 of 10

    For odd n the circular-minor cluster algebra CM_n is isomorphic to the Grassmannian cluster algebra A_{n-1,2n} after freezing/trivializing n central variables, relating circular total positivity to Grassmannian positi...

  3. Classification of Zamolodchikov periodic cluster algebras

    math.CO 2025-10 conditional novelty 7.0 of 10

    Zamolodchikov periodic B-matrices are in bijection with pairs of commuting finite-type Cartan matrices, with 29 new infinite families and 14 new exceptional types beyond the ADE case.

  4. Real $C$-, $G$-structures and sign-coherence of cluster algebras

    math.RT 2025-09 conditional novelty 7.0 of 10

    Real exchange matrices that are sign-coherent are characterized: quasi-integer type in general, and in rank 2 or finite type by Coxeter diagrams (sqrt(ab) = 2 cos(pi/m) or sqrt(ab) >= 2, and types A through I2(m)).

  5. Legendrian doubles, twist spuns, and clusters

    math.SG 2025-05 conditional novelty 6.0 of 10

    The authors construct cluster structures on sheaf moduli of twist-spun Legendrian surfaces and use them to produce new exact Lagrangian fillings and obstructions in contact R^5.
