Let p be an odd prime and \(H_k^{(n)}=\sum _{j=1}^k1/j^n\) denote the generalized harmonic number. In this paper, the authors establish a kind of congruences involving \(\sum _{k=1}^{p-1}k^mH_{k}^{(n)}\pmod {p^2}\), where mn are positive integers. Furthermore, the authors prove a congruence for \(\sum _{k=1}^{p-1}k^{p-2}(H_{k}^{(2)})^2\pmod {p^2}\).

模$$ p ^ 2 $$ p 2涉及广义调和数的同余

p为奇质数,\(H_k ^ {(n)} = \ sum _ {j = 1} ^ k1 / j ^ n \)表示广义谐波数。在本文中,作者建立了一个全等式,涉及\(\ sum _ {k = 1} ^ {p-1} k ^ mH_ {k} ^ {(n)} \ pmod {p ^ 2} \),其中m,  n是正整数。此外,作者证明了\(\ sum _ {k = 1} ^ {p-1} k ^ {p-2}(H_ {k} ^ {(2)})^ 2 \ pmod {p ^ 2} \)
