Koszul Algebras and Sheaves over Projective Space

We are going to show that the sheafication of graded Koszul modules over $Γ_{n} = K [x_{0}, x_{1} ... x_{n}]$ form an important subcategory $K \land_{Γ}$ of the coher…

Hochschild Cohomology of skew group rings and invariants

Eduardo do Nascimento Marcos, Roberto Martinez-Villa, Maria Izabel Ramalho Martins

Let $A$ be a $k$ -algebra and $G$ be a group acting on $A$ . We show that $G$ also acts on the Hochschild cohomology algebra $H H^{∙} (A)$ and that there is a monomorphism of rin…
