设{B-n(x)}表示伯努利多项式。本文通过确定Bk(p-1)+B(x)/(k(p- 1)+ B)(mod p(n),推广了库默的同余式,其中p是奇素数,x是p-整有理数,p-1 + B.作为应用,我们得到了Sigma(x=1)(p-1)(1/x(k))mod p(3)),Sigma(x=1)((p-1)/2)(1/x(k))(mod p(3)),(p - 1)!(mod p(3))和A(r)(m,p)(modp),其中k是{1,2,.,p - 1},A(r)(m,p)是同余式px = r(mod m)的最小正解.对于广义Bernoulli数{B-n,B-chi},我们也建立了类似的同余关系.

Let {B-n(x)} denote Bernoulli polynomials. In this paper we generalize Kummer's congruences by determining Bk(p-1)+b(x)/(k(p - 1) + b)(mod p(n), where p is an odd prime, x is a p-integral rational number and p -1 + b. As applications we obtain explicit formulae for Sigma(x=1)(p-1) (1/x(k)) mod p(3)), Sigma(x=1)((p-1)/2) (1/x(k))(mod p(3)), (p - 1)!(mod p(3)) and A(r)(m, p)(modp), where k is an element of {1,2,..., p - 1} and A(r)(m, p) is the least positive solution of the congruence px = r(mod m). We also establish similar congruences for generalized Bernoulli numbers {B-n,B-chi}. (C) 2000 Elsevier Science B.V. All rights reserved.
