Feb 14, 2013 at 19:35 comment added Yemon Choi I retagged your question. Note that if b is a rational multiple of a, then by rescaling you are just looking at the semigroup generated by two positive integers, and this is IIRC an example of a "numerical" subgroup, quite a lot is known (cf. "postage stamp" problems)
