Support theory for the small quantum group and the Springer resolution

Cris Negron, Julia Pevtsova

We consider the small quantum group u_q(G), for an almost-simple algebraic group G over the complex numbers and a root of unity q of sufficiently large order. We show that the Balm…

Support for integrable Hopf algebras via noncommutative hypersurfaces

Cris Negron, Julia Pevtsova

We consider finite-dimensional Hopf algebras $u$ which admit a smooth deformation $U \to u$ by a Noetherian Hopf algebra $U$ of finite global dimension. Examples of such Hopf algebr…

$A_{\infty}$ -coderivations and the Gerstenhaber bracket on Hochschild cohomology

C. Negron, Y. Volkov, S. Witherspoon

We show that Hochschild cohomology of an algebra over a field is a space of infinity coderivations on an arbitrary projective bimodule resolution of the algebra. The Gerstenhaber b…
