On the decomposition of extending modules
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.

Webules are unitary right modules. A submodule N of a module M is said to be essential in M ifNDK ^ 0 for every nonzero submodule K of M. A submodule C of M is called closed in M provided C has no proper essential extensions in M. A module M is a CS-module (or, as in [DHSW] and [O], an extending module) if and only if every closed submodule Web13 de mai. de 2016 · Extending (or CS) modules are generalizations of injective (and also semisimple or uniform) modules.
