Orbifold Hirzebruch-Riemann-Roch (2312.11493v1)
Published 3 Dec 2023 in math.AG
Abstract: We study the orbifold Hirzebruch-Riemann-Roch (HRR) theorem for quotient Deligne-Mumford stacks, explore its relation with the representation theory of finite groups, and derive a new orbifold HRR formula via an orbifold Mukai pairing.
