Tilting theory and functor categories I. Classical tilting

R. Martínez-Villa, M. Ortiz-Morales

Tilting theory has been a very important tool in the classification of finite dimensional algebras of finite and tame representation type, as well as, in many other branches of mat…

Tilting Theory and Functor Categories III. The Maps Category

R. Martinez-Villa, M. Ortiz-Morales

In this paper we continue the project of generalizing tilting theory to the category of contravariant functors $M o d (C)$ , from a skeletally small preadditive category $C$ to the cat…

Koszul Algebras and Sheaves over Projective Space

Roberto Martinez-Villa

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…
