Derived equivalences via Tate resolutions
K. Ganapathy, Sarang Sane
For any finite sequence of elements in a commutative noetherian ring , we show that for , the natural map from the Koszul complex $K(s_1^n, \ldots ,…

Ideal-theoretic non-noetherianity of polynomial functors in positive characteristic
Karthik Ganapathy
A long-standing open problem in representation stability is whether every finitely generated commutative algebra in the category of strict polynomial functors satisfies the noether…

Noncommutative invariants of finite and classical groups
Karthik Ganapathy
We investigate the structure of the invariant subring of the tensor algebra of a -representation , viewed as a twisted commutative algebra (tca). For a faithful repres…
