The Hirzebuch-Riemann-Roch (HRR) and Lefschetz type formulas for finite dimensional elementary algebras of finite global dimension are explicitly given. They have cohomological, homological, Hochschild cohomological and Hochschild homological four versions, and module, bimodule, module complex and bimodule complex four levels. For this, the dimension matrix of a bimodule (complex) and the trace matrix of a bimodule (complex) endomorphism are introduced. It is shown that Shklyarov pairing, Chern character and Hattori-Stallings trace can be concretely expressed by Cartan matrix, dimension vector and trace vector in this situation. Furthermore, the HRR and Lefschetz type formulas for finite dimensional elementary algebras of finite global dimension and dg algebras are compared.

  1. Protected corners and a trichotomy for Han's conjecture

    math.RT 2026-07 conditional novelty 7.0 of 10

    All three simples of a three-vertex Gap-A failure cannot all have infinite projective dimension; the two-infinite case is forced to be a 'mutual dumbbell', and a protected corner forces Ext^n(S_x,S_x) nonzero in every degree.

  2. $\tau$-Hochschild (co)homology, the square of the Serre bimodule, and the Coxeter automorphism of the Tamarkin--Tsygan calculus

    math.RT 2026-07 accept novelty 7.0 of 10

    τ-translates of the regular bimodule are the cycle modules of the Nakayama-twisted Happel resolution of the square of the Serre bimodule, linking τ-Hochschild theory to the Coxeter automorphism.
