Hochschild cohomology and lifts of endomorphisms

Niels Lauritzen, Jesper Funch Thomsen

We study when algebra endomorphisms can be lifted to first-order flat lifts. To a first-order flat lift of an algebra and an endomorphism, we associate a canonical class in Hochsch…

Lifts of endomorphisms of Weyl algebras modulo $p^{2}$

Niels Lauritzen, Jesper Funch Thomsen

Let $φ$ denote a $k$ -algebra endomorphism of the $n$ -th Weyl algebra $A_{n} (k)$ over a perfect field $k$ of positive characteristic $p$ . We prove that $φ$ can be lifted to an endomor…
