Abstract (EN):
Generalizations of Fine and Wilf's Periodicity Theorem are obtained for the case of bidimensional words using geometric arguments. The domains considered constitute a large class of convex subsets of R-2 which include most parallelograms. A complete discussion is provided,for the parallelogram case.
