On the integer part of the reciprocal of the Riemann zeta function tail at certain rational numbers in the critical strip

We prove that the integer part of the reciprocal of the tail of ζ(s) at a rational number s=1p for any integer with p≥ 5 or s=2p for any odd integer with p≥ 5 can be described essentially as the integer part of an explicit quantity corresponding to it. To deal with the case when s=2p, we use a result on the finiteness of integral points of certain curves over Q.
