Homotopy Invariants for gradable finite dimensional algebras
Sira Gratz, Theo Raedschelders, Špela Špenko +1
We show that for a gradable finite dimensional algebra the perfect complexes and bounded derived category cannot be distinguished by homotopy invariants.

Homotopy invariants of singularity categories
Sira Gratz, Greg Stevenson
We present a method for computing -homotopy invariants of singularity categories of rings admitting suitable gradings. Using this we describe any such invariant, e.g.…
