In mathematics, especially in the area of abstract algebra known as module theory, an injective module is a module Q that shares certain desirable properties with the Z-module Q of all rational numbers. Specifically, if Q is a submodule of some other module, then it is already a direct summand of that module; also, given a submodule of a module Y, then any module homomorphism from this submodule to Q can be extended to a homomorphism from all of Y to Q. This concept is dual to that of projective modules. Injective modules were introduced in (Baer 1940) and are discussed in some detail in the textbook (Lam 1999, §3).
Injective modules have been heavily studied, and a variety of additional notions are defined in terms of them: Injective cogenerators are injective modules that faithfully represent the entire category of modules. Injective resolutions measure how far from injective a module is in terms of the injective dimension and represent modules in the derived category. Injective hulls are maximal essential extensions, and turn out to be minimal injective extensions. Over a Noetherian ring, every injective module is uniquely a direct sum of indecomposable modules, and their structure is well understood. An injective module over one ring, may not be injective over another, but there are well-understood methods of changing rings which handle special cases. Rings which are themselves injective modules have a number of interesting properties and include rings such as group rings of finite groups over fields. Injective modules include divisible groups and are generalized by the notion of injective objects in category theory.
Baka totoo!! It will not cost us for sending this. This was on the 9:00 o'clock news the other night and this works. THIS TOOK TWO PAGES OF THE TUESDAY USA TODAY - IT IS FOR REALPLEEEEEEASE READ it was on the news!This thing is for real. Rest assured AOL and Intel will follow through with their...
I wanted to know if theres any or all globe/tm/smart promo out there that has no data cap for 1 month.
planning to get my lolo's fone the unlimited internet. He always watch movies in hir fone.
thanks you in advance
Bakit ganon na po ung Mobile Legends ko using Globe Switch Promos . Kasi pag naglalaro ako nakakatwo games lang ako . Sa unang game ko ayos pa naman pero pag second game ko na naglalag na ako kaya Afk ako lagi. Tapos pag itinatry ko ulit after an hour ganon na naman nangyayari.
Patips nga po ;)
