Axiomatics for generic categories in positive characteristic

Karthik Ganapathy

Generic categories arising in representation stability and equivariant commutative algebra are difficult to analyze in positive characteristic, as these categories rarely admit eno…

GL-algebras in positive characteristic III: the divided power algebra

Karthik Ganapathy

In this paper, we study GL-equivariant modules over the infinite-variable divided power algebra with an algebraically closed field of characteristi…

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…

Non-noetherian GL-algebras in characteristic two

Karthik Ganapathy

Over fields of characteristic two, we construct an infinite ascending chain of GL-stable ideals in the coordinate ring of infinite skew-symmetric matrices. This construction provid…

Resolutions of symmetric ideals via stratifications of derived categories

Karthik Ganapathy

We propose a method to unify various stability results about symmetric ideals in polynomial rings by stratifying related derived categories. We execute this idea for chains of $GL_…
