Universal deformation rings and derived equivalences

Shengyong Pan

In this paper, we show that stable functors of derived equivalences preserve the isomorphism classes of versal deformation rings of finitely generated Gorenstein-projective modules…

On universal deformation rings and stable equivalences of Gorenstein-projective modules

Shengyong Pan, Jose A. Velez-Marulanda

Let $k$ be a field and let $I^$ and $I^$ finite dimensional $k$ -algebras. Assume that $_{I^} X_{I^} $ and $_{I^} Y_{I^} $ are bimodules that define a singular equivalence…
