✦ Synopsis


In this article, we deal with a connectivity problem stated by Maurer and Slater to characterize minimally k-edge'-connected graphs. This problem has been solved for k = 1,2 and 3, and we recall herein the results obtained. Then we give some partial results concerning the case k =4: representation of graphs of order 4 or 5, characterization of graphs with minimum degree 2 and without vertices of degree 3, characterization of quasi-cubic graphs.

## Abstract For an integer __l__ > 1, the __l__‐edge‐connectivity of a connected graph with at least __l__ vertices is the smallest number of edges whose removal results in a graph with __l__ components. A connected graph __G__ is (__k__, __l__)‐edge‐connected if the __l__‐edge‐connectivity of __G_

A graph G is (n, \*)-connected if it satisfies the following conditions: (1) |V(G)| n+1; (2) for any subset S V(G) and any subset L E(G) with \* |S| +|L| <n\*, G&S&L is connected. The (n, \*)-connectivity is a common extension of both the vertex-connectivity and the edge-connectivity. An (n, 1)-conn

## Abstract Let __v__ be an arbitrary vertex of a 4‐edge‐connected Eulerian graph __G__. First we show the existence of a nonseparating cycle decompositiion of __G__ with respect to __v__. With the help of this decomposition we are then able to construct 4 edge‐independent spanning trees with the c

## Abstract Let γ(__G__) be the domination number of graph __G__, thus a graph __G__ is __k__‐edge‐critical if γ (__G__) = k, and for every nonadjacent pair of vertices __u__ and υ, γ(__G__ + __u__υ) = k−1. In Chapter 16 of the book “Domination in Graphs—Advanced Topics,” D. Sumner cites a conjectu
