Let G be a minimally k-edge-connected simple graph and u\*(G) be the number of vertices of degree k in G. proved that (i) uk(G) 2 l(jGl -1)/(2k + l)] + k + 1 for even k, and (ii) uI(G) 2 [lGl/(k + l)] + k for odd k 35 and u,(G) 2 lZlGl/(k + l)] + k -2 for odd k 27, where ICI denotes the number of v
Let k be a positive integer, and D = (V (D), E(D)) be a minimally k-edge-connected simple digraph. We denote the outdegree and indegree of x ∈ V (D) by δ D (x) and ρ D (x), respectively. Let u + (D) denote the number of vertices W. Mader asked the following question in [Mader, in Paul Erdös is Eigh
We improve a result of Liebeck and Saxl concerning the minimal degree of a primitive permutation group and use it to strengthen a result of Guralnick and Neubauer on generic covers of Riemann surfaces.
