Module concept is a vital software for plenty of various branches of arithmetic, in addition to being a fascinating topic in its personal correct. inside module thought, the concept that of injective modules is especially very important. Extending modules shape a traditional type of modules that's extra common than the category of injective modules yet keeps lots of its fascinating houses. This booklet gathers jointly for the 1st time in a single position contemporary paintings on extending modules. it's geared toward a person with a easy wisdom of ring and module conception
