The edges of the Cartesian product of graphs G x H a r e to be colored with the condition that all rectangles, i.e., K2 x K2 subgraphs, must be colored with four distinct colors. The minimum number of colors in such colorings is determined for all pairs of graphs except when G is 5-chromatic and H

## Abstract The topological approach to the study of infinite graphs of Diestel and KΓhn has enabled several results on Hamilton cycles in finite graphs to be extended to locally finite graphs. We consider the result that the line graph of a finite 4βedgeβconnected graph is hamiltonian. We prove a
## Abstract By a result of Gallai, every finite graph __G__ has a vertex partition into two parts each inducing an element of its cycle space. This fails for infinite graphs if, as usual, the cycle space is defined as the span of the edge sets of finite cycles in __G__. However, we show that, for t
The problem of an edge crack in a finite orthotropic plate under anti-plane shear is considered. The boundary collocation method is used to calculate the mode III stress intensity factor (SF). For the case in which the material is isotropic, the present results agree very well with those obtained by
