Résumé :
Extensions and variations of the basic problem of graph coloring are
introduced. It consists essentially in finding in a graph G a k-coloring, i.e.,
a partition V 1, ..., V k of the vertex set of G such that for some specified
neighborhood ˜N (v) of each vertex v, the number of vertices in ˜N (v) \ V i
is (at most) a given integer hi
v. The complexity of some variations is
discussed according to ˜N (v) which may be the usual neighbors, or the
vertices at distance at most 2 or the closed neighborhood of v (v and its
neighbors). Polynomially solvable cases are exhibited (in particular when
G is a special tree).
