- Abstract:
-
The main result of this paper is the decidability of the membership problem for 2 × 2 nonsingular integer matrices. Namely, we will construct the first algorithm that for any nonsingular 2 × 2 integer matrices M1 : : : Mn and M decides whether M belongs to the semigroup generated by fM1 : : : Mng. Our algorithm relies on a translation of nu- merical problems on matrices into combinatorial problems on words. It also makes use of some algebraic properties of well-known subgroups of GL(2; Z) and...
