Endomorphismenringe von Permutationsmoduln auf den Nebenklassen einer p-Sylowgruppe
… J. L. Alperin himself has proposed to analyse endomorphism rings of permutation modules of groups on the cosets on its Sylow-p-subgroup. This thesis contributes to this approach. At first, fundamental elements of the ordinary and modular representation theory of such endomorphism rings are …

Modular Temperley-Lieb Theory
… are still cellular and can be considered as endomorphism rings of tensor products of indecomposable Uq(𝔰𝔩₂)-modules in the given characteristic. We determine the cellular data for a number of classes of such truncations and give indications of a general, if computationally intensive, approach …

Analysis and Implementation of Algorithms for Noncommutative Algebra
… are discussed. A new algorithm for constructing endomorphism rings of modules defined over path algebras is presented. This algorithm is shown to have better performance than previously used algorithms. Finally, a linear time algorithm, to determine whether a quotient of a path algebra, with a …

Computing the trace of an endomorphism of a supersingular elliptic curve
… explicit algorithm for computing the trace of an endomorphism of an elliptic curve which is given by a chain of small-degree isogenies. We analyze its complexity, determining that if the length of the chain, the degree of the isogenies, and the log of the field-size are all O(n), the trace of the …
