We characterize the universal central extension of a perfect precrossed module giving two descriptions, one in terms of non-abelian tensor products of groups and other in terms of projective presentations. As application to relative algebraic K-theory, we obtain that Milnor's absolute and relative K

Let G = (V (G), E(G)) be a simple graph of maximum degree ∆ ≤ D such that the graph induced by vertices of degree D is either a null graph or is empty. We give an upper bound on the number of colours needed to colour a subset S of V (G) ∪ E(G) such that no adjacent or incident elements of S receive
An extension of Carlson's inequality is made by using the Euler-Maclaurin summation formula. The integral analogues of this inequality are also presented. 2002 Elsevier Science (USA)
## An upper bound for P[W=O], where W is a sum of indicator variables with a special structure, which appears, for example, in subgraph counts in random graphs, is derived. Furthermore, its applications to a problem of k-runs and a random graph problem are given. The result is a generalization and
