## Abstract Regarding an infinite planar graph __G__ as a discrete analogue of a noncompact simply connected Riemannian surface, we introduce the combinatorial curvature of __G__ corresponding to the sectional curvature of a manifold. We show this curvature has the property that its negative values

We present a planar hypohamiltonian graph on 42 vertices and (as a corollary) a planar hypotraceable graph on 162 vertices, improving the bounds of Zamfirescu and Zamfirescu and show some other consequences. We also settle the open problem whether there exists a positive integer N, such that for eve
A 3-valent graph G 1s cyclically n-connected provided one must cut at least n edges in ori4r to separate any two circuits of 6. If G is cyclically n-connected but any separation of G by cutting n edges yields a component consisting of a simple circuit, then we say that G is ' strong& cyclicaZZy n-co
Survey of various problems about combinatorial games. ## O. Introduction A combinatorial game is the situation where two players, usually called A and B, play alternately by selecting an element in a finite set X according to fixed rules; the first player to achieve a certain configuration has wo
This paper generalizes a theorem of Thomassen on paths in planar graphs. As a corollary, it is shown that every 4-connected planar graph has a Hamilton path between any two specified vertices x, y and containing any specified edge other than xy.
