## Some preliminaries In this section we define some of the terms used in the paper and state some results for later use. All rings considered in this paper are commutative and Noetherian and all modules considered are assumed to be finitely generated. For a module M over a ring, ยต(M) will denote t
The cohomology groups of the Seifert manifolds are well known. In this article a method is given to compute the cup products in the cohomology ring of any orientable Seifert manifold whose associated orbit surface is S 2 , and for any coefficients. In particular the Z/2 cohomology ring is completely
