Abstract

Let p>5p>5 be a prime. We prove congruences modulo p3dp^{3-d} for sums of the general form k=0(p3)/2(2kk)tk/(2k+1)d+1\sum_{k=0}^{(p-3)/2}\binom{2k}{k}t^k/(2k+1)^{d+1} and k=1(p1)/2(2kk)tk/kd\sum_{k=1}^{(p-1)/2}\binom{2k}{k}t^k/k^d with d=0,1d=0,1. We also consider the special case t=(1)d/16t=(-1)^{d}/16 of the former sum, where the congruences hold modulo p5dp^{5-d}.
