Bi-interpretability with ℤ and models of the complete elementary theories of SL_n(O), T_n(O) and GL_n(O), n ≥ 3

Submission date: 7 April 2020


Let O be the ring of integers of a number field, and let n ≥ 3. This paper studies bi-interpretability of the ring of integers ℤ with the special linear group SL_n(O), the general linear group GL_n(O) and solvable group of all invertible uppertriangular matrices over O, T_n(O). For each of these groups we provide a complete characterization of arbitrary models of their complete elementary theories.
