Tilting theoretic approach to quasi-hereditary structures

Takahide Adachi, Aaron Chan, Yuta Kimura +1

A quasi-hereditary algebra is an algebra equipped with a certain partial order $⊴$ on its simple modules. Such a partial order -- called a quasi-hereditary structure -- gives…

Schur roots and tilting modules of acyclic quivers over commutative rings

Osamu Iyama, Yuta Kimura

Let $Q$ be a finite acyclic quiver and $A_{Q}$ the cluster algebra of $Q$ . It is well-known that for each field $k$ , the additive equivalence classes of support tilting $k Q$ -modules…

$τ$ -tilting theory and silting theory of skew group algebra extensions

Yuta Kimura, Ryotaro Koshio, Yuta Kozakai +2

Let $Λ$ be a finite dimensional algebra with an action by a finite group $G$ and $A := Λ * G$ the skew group algebra. One of our main results asserts that the canonical restriction-in…

Cohen-Macaulay representations of Artin-Schelter Gorenstein algebras of dimension one

Osamu Iyama, Yuta Kimura, Kenta Ueyama

Tilting theory is one of the central tools in modern representation theory, in particular in the study of Cohen-Macaulay representations. We study Cohen-Macaulay representations of…
