Witrynacategories of left R-modules and left S-modules are equivalent. In a series of seminal papers, Marc Rie↵el developed a very useful notation of Morita equivalence for C*-algebras in the 70s. 2 Imprimitivity bimodules Definition 2.1. Let A and B be C*-algebras. Then anA-B-imprimitivity bimodule (A-B-equivalence bimodule) is an A-B … Witryna15 sty 2015 · The determination of the decomposition matrices and the study of the modular structure of permutation modules are two important open problems in the representation theory of symmetric groups. Young permutation modules were deeply studied by James in [13], Klyachko in [16] and Grabmeier in [10].

In abstract algebra, a decomposition of a module is a way to write a module as a direct sum of modules. A type of a decomposition is often used to define or characterize modules: for example, a semisimple module is a module that has a decomposition into simple modules. Given a ring, the types of decomposition of modules over the ring can also be used to define or characterize the ring: a ring is semisimple if and only if every module over it is a semisimple module. WitrynaThis tensor product decomposition of the imprimitivit! algebra arises from a tensor product decomposition, of some interest in itself, of the “imprimitivity bimodule” (as … galvanised bolts and nuts
