Torsion algebras of Hermitian manifolds and rigidity
Wangyang Lin, Yibo Ren
We regard the Chern torsion of a Hermitian manifold as a skew-symmetric complex-bilinear product on its holomorphic tangent bundle. For a compact connected Chern--Kähler-like Hermi…

Inequalities for Chow Polynomials and Chern Numbers of Matroids
Ronnie Cheng, Wangyang Lin
The Chow polynomial of a matroid is a fundamental invariant whose coefficients exhibit strong positivity properties, including -positivity. We interpret the normalized Chow coef…

Explicit formulas for the Hattori-Stong theorem and applications
Ping Li, Wangyang Lin
We employ combinatorial techniques to present an explicit formula for the coefficients in front of Chern classes involving in the Hattori-Stong integrability conditions. We also gi…
