"The concept of system of imprimitivity is used in mathematics, particularly in algebra and analysis, both within the context of the theory of group representations. It was used by George Mackey as the basis for his theory of induced unitary representations of locally compact groups. The simplest case, and the context in which the idea was first noticed, is that of finite groups (see primitive permutation group). Consider a group G and subgroups H and K, with K contained in … " - Imprimitivity decomposition of module

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. Witryna20 kwi 2024 · A standard strategy in tackling different problems involving such graphs consists in employing a reduction process involving quotients with respect to imprimitivity block systems, preferably those arising from normal intransitive subgroups. But such reductions are not always possible.

WitrynaIndecomposable module. In abstract algebra, a module is indecomposable if it is non-zero and cannot be written as a direct sum of two non-zero submodules. [1] Indecomposable is a weaker notion than simple module (which is also sometimes called irreducible module): simple means "no proper submodule" , while indecomposable … Witryna20 paź 2024 · In general, a representation of $G$ is imprimitive with a decomposition into $k$ blocks, if and only if it is induced from a subgroup of $G$ of index $k$.

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.
