## Abstract A graph __H__ is a cover of a graph __G__ if there exists a mapping ฯ from V(__H__) onto V(__G__) such that ฯ maps the neighbors of every vertex ฯ in __H__ bijectively to the neighbors of ฯ(ฯ ) in __G__. Negami conjectured in 1986 that a connected graph has a finite planar cover if and o

It is easy to see that planar graphs without 3-cycles are 3-degenerate. Recently, it was proved that planar graphs without 5-cycles are also 3-degenerate. In this paper it is shown, more surprisingly, that the same holds for planar graphs without 6-cycles.
## Abstract It is well known that every planar graph __G__ is 2โcolorable in such a way that no 3โcycle of __G__ is monochromatic. In this paper, we prove that __G__ has a 2โcoloring such that no cycle of length 3 or 4 is monochromatic. The complete graph __K__~5~ does not admit such a coloring. On

Given a weighted undirected graph G and a subgraph S of G, we consider the problem of adding a minimum-weight set of edges of G to S so that the resulting ลฝ . subgraph satisfies specified edge or vertex connectivity requirements between pairs of nodes of S. This has important applications in upgradi
