On compatibility of Koszul- and higher preprojective gradings

Darius Dramburg, Mads Hustad Sandøy

We investigate compatibility of gradings for an almost Koszul or Koszul algebra $R$ that is also the higher preprojective algebra $Π_{n + 1} (A)$ of an $n$ -hereditary algebra $A$ . For…

A classification of $n$ -representation infinite algebras of type Ã

Darius Dramburg, Oleksandra Gasanova

We classify $n$ -representation infinite algebras $Λ$ of type Ã. This type is defined by requiring that $Λ$ has higher preprojective algebra $Π_{n+1}(Λ) \simeq k[x_1, \ldots, x_{n+1…

The 3-Preprojective Algebras Of Type $A ~$

Darius Dramburg, Oleksandra Gasanova

Let $G \leq SL_{n + 1} (C)$ act on $R = C [X_{1}, \dots, X_{n + 1}]$ by change of variables. Then, the skew-group algebra $R * G$ is bimodule $(n + 1)$ -C…
