We show the following. (1) For each integer n> 12, there exists a uniquely 3-colorable graph with n vertices and without any triangles. (2) There exist infinitely many uniquely 3-colorable regular graphs without any triangles. It follows that there exist infinitely many uniquely k-colorable regular

In this paper we contribute to the understanding of the geometric properties of 3D drawings. Namely, we show how to make a 3D straight-line grid drawing of 4-colorable graphs in 0( n\*) volume. Moreover, we prove that each bipartite graph needs at least a( n3/\*) volume. @
In [2], for each non-negative integer k, we constructed a connected graph with (24)2k vertices which is uniquely 3-colorable, regular with degree k+5, and triangle-free. Here, for each positive integer n and each integer r > 5, we construct a connected graph with (26)n .2'-' vertices which is unique
We discover a surprising connection between graph coloring in two orthogonal paradigms: parallel and on-line computing. We present a randomized on-line Ε½ . coloring algorithm with a performance ratio of O nrlog n , an improvement of log n factor over the previous best known algorithm of Vishwanathan
