Algorithms for the Tits alternative and related problems

A. S. Detinko, D. L. Flannery, E. A. O'Brien

We present an algorithm that decides whether a finitely generated linear group over an infinite field is solvable-by-finite: a computationally effective version of the Tits alterna…

Recognizing finite matrix groups over infinite fields

A. S. Detinko, D. L. Flannery, E. A. O'Brien

We present a uniform methodology for computing with finitely generated matrix groups over any infinite field. As one application, we completely solve the problem of deciding finite…

Algorithms for linear groups of finite rank

A. S. Detinko, D. L. Flannery, E. A. O'Brien

Let G be a finitely generated solvable-by-finite linear group. We present an algorithm to compute the torsion-free rank of G and a bound on the Prüfer rank of G. This yields…
