Quiver Heisenberg algebras: a cubic analogue of preprojective algebras
Martin Herschend, Hiroyuki Minamoto
In this paper we study a certain class of central extensions of preprojective algebras of quivers under the name quiver Heisenberg algebras (QHA). There are several classes of alge…

Serre duality, Mukai pairing and universal Auslander--Reiten triangle
Hiroyuki Minamoto
We study the relationship between Serre duality and the Mukai pairing for smooth and proper dg-algebras. We introduce an alternative definition of the Mukai pairing and prove that…

-tilting theory and silting theory of skew group algebra extensions
Yuta Kimura, Ryotaro Koshio, Yuta Kozakai +2
Let be a finite dimensional algebra with an action by a finite group and the skew group algebra. One of our main results asserts that the canonical restriction-…
