一类含有调和数的同余式
Several congruences involving harmonic numbers
摘要
Abstract
The purpose of this paper is to establish several congruences involving harmonic numbers.Let p>3 be a prime.With the help of some combinatorial identities and congruences,the following congruences is generated:∑p-1k=1k2H2k ≡ p-4/9 (mod p2) and ∑p-1k=1k2H2k ≡23/18 (mod p).The congruences are also established as ∑(p-1)/2k=1H2k/k≡-8/3q3p(2) +1/6Bp-3(mod p)and ∑(p-1)/2k=1H22k ≡-1+1/2q2p(2) (mod p),where Bn(n ∈ N) are Bernoulli numbers and qp(a) =(ap-1-1)/p is usually called a Fermat quotient provided p a.关键词
