Imprimitivity decomposition of module
WitrynaTour Start here for a quick overview of the site Help Center Detailed answers to any questions you might have Meta Discuss the workings and policies of this site 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.

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]. Witrynamodules Z1, Z2, and Z3, where D(Z) is the standard dual of Z. By using the above facts, we can determine indecomposable decomposition of all tensor products of indecomposable Uq(sl2)-modules in explicit formulas. As a by-product, it is shown that Uq(sl2)-mod is not a braided tensor category if p ≥ 3.
