Patch Colorings and Rigid Colorings of the Rational n-Space
2002
Journal of combinatorial theory. Series B (Print)
Preserved Fulltext
We investigate k-colorings of the rational n-space, Q n , such that any two points at distance one get distinct colors. ...
We prove that the existence of a patch k-coloring of Q n implies the existence of a k-coloring of R n . We show that every 2-coloring of Q 2 or Q 3 , and every 4-coloring of Q 4 is rigid. ...
ACKNOWLEDGMENTS The authors are grateful to both referees for the careful reading and for their helpful comments. ...
