✦ Synopsis
Graphs with n + k vertices in which every set of n +j vertices induce a subgraph of maximum degree at least n are considered.
For j = 1 and for k fairly small compared to n, we determine the minimum number of edges in such graphs.

Vizing's Theorem, any graph G has chromatic index equal either to its maximum degree A(G) or A(G) + 1. A simple method is given for determining exactly the chromatic index of any graph with 2s + 2 vertices and maximum degree 2s.
## Abstract In 1968, Vizing [Uaspekhi Mat Nauk 23 (1968) 117–134; Russian Math Surveys 23 (1968), 125–142] conjectured that for any edge chromatic critical graph ${{G}} = ({{V}}, {{E}})$ with maximum degree $\Delta$, $|{{E}}| \geq {{{1}}\over {{2}}}\{(\Delta {{- 1}})|{{V}}| + {{3}}\}$. This conject
Let G be a simple graph of order n without isolated vertices. If the integer h satisfies In this note the maximum size of Sri(h)--graphs is determined. A result of Krol and Veldman on critically h-connected graphs follows as a corollary.

## Abstract A graph __G__ is (__k__,0)‐colorable if its vertices can be partitioned into subsets __V__~1~ and __V__~2~ such that in __G__[__V__~1~] every vertex has degree at most __k__, while __G__[__V__~2~] is edgeless. For every integer __k__⩾0, we prove that every graph with the maximum average
