Abstract
Let p>3 be a prime. In this paper, we obtain the congruences for k=0∑p−1(−8)kw(k)(k2k)3, k=0∑p−1(−192)kw(k)(k2k)2(k3k), k=0∑p−1(−144)kw(k)(k2k)2(2k4k) and k=0∑p−1648kw(k)(k2k)2(2k4k) modulo p2, and partial results for ∑k=0(p−1)/2(k2k)3mkw(k) modulo p2, where m∈{1,16,−64,256,−512,4096} and w(k)∈{k2,k3,k+11,(k+1)21,(k+1)31,2k−11,k+21}.
