Abstract

We present a construction to simulate Turing machines with 3×3 matrices over rationals. The correctness of simulation is guaranteed by testing that the matrices have integral elements during the simulation. This construction implies an undecidability result for a special identity problem for semigroups of 3×3-matrices.
