Abstract

We develop a practical algorithm to decide whether a finitely generated subgroup of a solvable algebraic group GG is arithmetic. This incorporates a procedure to compute a generating set of an arithmetic subgroup of GG. We also provide a simple new algorithm for integrality testing of finitely generated solvable-by-finite linear groups over the rational field. The algorithms have been implemented in {\sc Magma}.
