Abstract:

Subdivisions of a plane into fundamental regions for two-dimensional Fedorov groups are studied, and all possible contiguity symbols are determined which set those motions by means of which a given fundamental region passes over into re gions contiguous to it. The work shows that the entire problem is combinatorially topological, and thus a new purely topological conclusion for twodimensional Fedorov groups is obtained. The following theorem is proved There are only 11 eleven topologically different regular grids which satisfy the basic lemma of integral calculus. Author
