Euclidean components for a class of self-injective algebras
Sarah Scherotzke
We determine the length of composition series of projective modules of G-transitive algebras with an Auslander-Reiten component of Euclidean tree class. Furthermore we show that mo…

Formulas for primitive Idempotents in Frobenius Algebras and an Application to Decomposition maps
Max Neunhoeffer, Sarah Scherotzke
In the first part of this paper we present explicit formulas for primitive idempotents in arbitrary Frobenius algebras using the entries of representing matrices coming from projec…
