Algebraic K-theory — In mathematics, algebraic K theory is an important part of homological algebra concerned with defining and applying a sequence Kn(R) of functors from rings to abelian groups, for all integers n. For historical reasons, the lower K groups K0 and… … Wikipedia
Semi-symmetric graph — In mathematics, a semi symmetric graph is an undirected graph that is edge transitive and regular, but not vertex transitive.In other words, a graph is semi symmetric if each vertex has the same number of incident edges, and there is a symmetry… … Wikipedia
Semi-local ring — In mathematics, a semi local ring is a ring with a finite number of maximal ideals. It must be said that some refer to such a ring in general as a quasi local ring, using semi local ring to refer to a Noetherian ring with finitely many maximal… … Wikipedia
