-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-in…
A characterization for induced modules to be support -tilting modules
Ryotaro Koshio, Yuta Kozakai
Let be a finite group and a normal subgroup of . In this paper, we give a necessary and sufficient condition for to be a su…
Normal subgroups and support -tilting modules
Ryotaro Koshio, Yuta Kozakai
Let be a finite group, a normal subgroup of and an algebraically closed field of characteristic . The first main result in this paper is to sho…
On induced modules of inertial-invariant support -tilting modules over blocks of finite groups
Ryotaro Koshio
In this article, we prove that induced modules of support -tilting modules over blocks of finite groups satisfying inertial-invariant condition are also support -tilting modu…
Induced modules of support -tilting modules and extending modules of semibricks over blocks of finite groups
Ryotaro Koshio, Yuta Kozakai
In this article we study support -tilting modules, semibricks and more over blocks of group algebras. Let be an algebraically closed field of characteristic , $\tilde{G…
On support -tilting modules over blocks covering cyclic blocks
Ryotaro Koshio, Yuta Kozakai
Support -tilting modules correspond to some classes of categorical objects bijectively, such as two-term tilting complexes for any finite dimensional symmetric algebra. This fac…
