Silting and Tilting for Weakly Symmetric Algebras
Jenny August, Alex Dugas
If A is a finite-dimensional symmetric algebra, then it is well-known that the only silting complexes in are the tilting complexes. In this note we i…

Some algebras that are not silting connected
Alex Dugas
We give examples of finite-dimensional algebras for which the silting objects in $K^b(\mbox{proj-}A)$ are not connected by any sequence of (possibly reducible) silting mutation…

Gradable modules over artinian rings
Alex Dugas
Let be a -graded artin algebra. Two classical results of Gordon and Green state that if has only finitely many indecomposable gradable modules, up to isomorphis…
