Title
On Minimum Vertex Covers Of Generalized Petersen Graphs
Abstract
For natural numbers n and k (n > 2k), a generalized Petersen graph P (n, k), is defined by vertex set {u(i), v(i)} and edge set {u(i)u(i+1), u(i)v(i), v(i)v(i+k)}; where i = 1, 2,..., n and subscripts are reduced modulo n. Here first, we characterize minimum vertex covers in generalized Petersen graphs. Second, we present a lower bound and some upper bounds for beta(P (n, k)), the size of minimum vertex cover of P (n, k). Third, in some cases, we determine the exact values of beta(P(n, k)). Our conjecture is that beta(P (n, k)) <= n + [n/5], for all n and k.
