$2$ -representation infinite algebras from non-abelian subgroups of $SL_{3}$ . Part II: Central extensions and exceptionals

Darius Dramburg

Let $G \leq SL_{3} (C)$ be a non-trivial finite group, acting on $R = C [x_{1}, x_{2}, x_{3}]$ . We continue our investigation from arXiv:2505.10683 [math.RT]…

$2$ -representation infinite algebras from non-abelian subgroups of $SL_{3}$ . Part I: Extensions of abelian groups

Darius Dramburg, Oleksandra Gasanova

Let $G \leq SL_{3} (C)$ be a non-trivial finite group, acting on $R = C [x_{1}, x_{2}, x_{3}]$ . The resulting skew-group algebra $R * G$ is $3$ -Calabi-Yau…

On the Orbifold origin of Higher Form Symmetries in Geometric Engineering

Darius Dramburg, Shani Nadir Meynet, Andrea Sangiovanni

In this work we explore the relation between orbifold singularities and higher form symmetries. Using the geometric engineering dictionary, we argue that the discrete higher symmet…

On compatibility of Koszul- and higher preprojective gradings

Darius Dramburg, Mads Hustad SandÃ¸y

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

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

Darius Dramburg, Oleksandra Gasanova

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