Abstract: | We construct simultaneous rational approximations to q-series L1(x1; q) and L1(x2; q) and, if x = x1 = x2, to series L1(x; q) and L2(x; q), where . Applying the construction, we obtain quantitative linear independence over ℚ of the numbers in the following collections:
1, ζq(1) = L1(1; q),
and 1, ζq(1), ζq(2) = L2(1; q) for q = 1/p, p ε ℤ \ {0,±1}. Bibliography: 14 titles.
