Structure of bauer's groups of commutative rings

Galua's theory of commutative rings is investigated in the paper aiming at the structure description of a Bauer's group of regular half-local rings of geometrical type with the help of generating lines and relations. As a result the theorem of Merkuriev - Suslin about the homomorphism bijectiveness of a norm residue has been generalized for the case of commutative rings. The structure description of Bauer's group of a main ring has been obtained with the help of generating lines and relationsAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
