Abstract: Abstract One of the main problems in representation theory is to understand the exact relationship between Brauer corresponding blocks of finite groups. The case where the local correspondent has a unique simple module seems key.… read more here.

DOI: 10.1016/j.jalgebra.2019.10.016
Abstract: Abstract In this paper, we introduce the notion of generalized Brauer morphism for F G -modules with respect to a p-subgroup of G. This generalization is based on p-indecomposable decompositions of F G -modules. The… read more here.

DOI: 10.1134/s106456242106017x
Abstract: We show that a quotient of a non-trivial Severi–Brauer surface S over arbitrary field k of characteristic 0 by a finite group G ⊂ Aut(S) is k-rational, if and only if |G| is divisible by… read more here.

Abstract: A study of the type series of Stylophthalmus paradoxus and Idiacanthus atlanticus (Stomiidae), and Cyclothone livida, C. obscura and C. pallida (Gonostomatidae), uncovered errors in the synonymy of Idiacanthus and inconsistencies regarding the number of… read more here.
