Summary:
For any Galois extension K/k of number fields, we show that
every Artin L-function for Gal(K/k) is holomorphic at
s = s0 ≠ 1 whenever the quotient ζK(s)/ζ k(s) of
Dedekind zeta functions has a zero of order at most max {2, p2
-2} at s = s0 (here p2 stands for the second smallest prime
divisor of [K:k]). This result gives a refinement of the
previous work of Foote and V. K. Murty.
