Abstract

For a given finitely generated multiplicative subgroup of the rationals which possiblycontain negative numbers, we derive, subject to GRH, formulas for the densities of primes forwhich the index of the reduction group has a given value. We completely classify the cases of rankone, torsion groups for which the density vanishes and the the set of primes for which the indexof the reduction group has a given value, is finite. For higher rank groups we propose some partialresults. Finally, we present some computations comparing the approximated density computedwith primes up to1010and those predicted by the Riemann Hypothesis
