Riemann-Roch for stacky matrix factorizations
Dongwook Choa, Bumsig Kim, Bhamidi Sreedhar
We establish a Hirzebruch-Riemann-Roch type theorem and Grothendieck-Riemann-Roch type theorem for matrix factorizations on quotient Deligne-Mumford stacks. For this we first const…

Virtual equivariant Grothendieck-Riemann-Roch formula
Charanya Ravi, Bhamidi Sreedhar
For a -scheme with a given equivariant perfect obstruction theory, we prove a virtual equivariant Grothendieck-Riemann-Roch formula, this is an extension of a result of Fant…

Localization by 2-periodic complexes and virtual structure sheaves
Jeongseok Oh, Bhamidi Sreedhar
B. Kim and the first author proved a result comparing the virtual fundamental classes of the moduli spaces of stable quasimaps and stable LG-quasimaps by studying localized Chern c…
