Simple modules over finite twisted category algebras.
The recent proof, by Ganyushkin, Mazorchuk and Steinberg, ofthe parametrisation of simple modules over finite semigroup algebrasdue to Cliford, Munn and Ponizovskii carries over to twisted finite category algebras.Since some well known combinatorially defined algebras, such as Brauer orTemperley-Lieb algebras, are in fact twisted semigroup algebras, the parametrisationsgiven by Graham and Lehrer can be obtained as special cases of presented result.
