Ideals and Reality Breitscheidstr. 10 denn diese [¿]Besides giving an introduction to Commutative Algebra the theory of c mutative rings this book is devoted to the study of projective modules and the minimal number of generators of modules and ideals. The notion of a module over a ring R is a generalization of that of a vector space over a field k. The axioms are identical. But whereas every vector space possesses a basis, a module need not always have one. Modules possessing a basis are called free.
