## Abstract By Petersen's theorem, a bridgeless cubic graph has a 2‐factor. H. Fleischner extended this result to bridgeless graphs of minimum degree at least three by showing that every such graph has a spanning even subgraph. Our main result is that, under the stronger hypothesis of 3‐edge‐connec

✦ Synopsis
For any positive integer s, an s-partition of a graph G = ( ! -( €I is a partition of E into El U E2 U U E k, where 14 = s for 1 I i 5 k -1 and 1 5 1 4 1 5 s and each €; induces a connected subgraph of G. We prove (i) if G is connected, then there exists a 2-partition, but not neces-(ii) if G is 2-edge connected, then there exists a 3-partition, but not (iii) if G is 3-edge connected, then there exists a 4-partition;
(iv) if G is 4-edge connected, then there exists an s-partition for all S.

In this paper, we establish that any interval graph (resp. circulararc graph) with n vertices admits a partition into at most log 3 n (resp. log 3 n +1) proper interval subgraphs, for n>1. The proof is constructive and provides an efficient algorithm to compute such a partition. On the other hand, t
## Abstract A graph has the neighbor‐closed‐co‐neighbor, or ncc property, if for each of its vertices __x__, the subgraph induced by the neighbor set of __x__ is isomorphic to the subgraph induced by the closed non‐neighbor set of __x__. As proved by Bonato and Nowakowski [5], graphs with the ncc p
The partitioning of a rectangular grid graph with weighted vertices into p connected components such that the component of smallest weight is as heavy as possible (the max-min problem) is considered. It is shown that the problem is NP-hard for rectangles with at least three rows. A shifting algorith
If G is a graph on n vertices and r 2 2, w e let m,(G) denote the minimum number of complete multipartite subgraphs, with r or fewer parts, needed to partition the edge set, f(G). In determining m,(G), w e may assume that no two vertices of G have the same neighbor set. For such reduced graphs G, w
