摘要
Mare Chamberland和Karl Dilcher[Divisibility properties of a class of binomial sums,J.Number Theory,120(2006)pp.349-371]研究了一类二项式和uεa,b(n)并给出了一些有趣的性质,其中uεa,b(n)=∑nk=0(-1)εk(kn)a(2kn)b,对a,b,n∈N和ε∈{0,1}.最后,他们提出了uaε,b(n)的一种推广,即uεa,b,c(n)=∑nk=0(-1)εk(kn)a(2kn)b(3kn)c,其中a,b,c,n∈N,ε∈{0,1},期望uεa,b,c(n)具有与uaε,b(n)相似的性质,但并未给出具体的性质及证明.在本文中,我们给出并证明了uεa,b,c(n)的与Wolstenhol me定理有关的这部分性质.
Mare Chamberland and Karl Dilcher [Divisibility properties of a class of binomial sums, J. Number Theory, 120(2006), pp. 349 - 37] ] studied ua^ε,b(n) and gave some interesting properties, where
ua^ε,b(n)=∑k-1^0(-1)εk(k^n)^a(k^2n)^b
for a, b, n ∈ N and ε∈ {0,1 }. At the end of their paper, they suggested a generalization of u^εa,b(n ), namely
ua^ε,b(n)=∑k-1^0(-1)εk(k^n)^a(k^2n)^b
wherea,b,c,n ∈ N and ε∈ {0,1}. They expected that ua^ε,b,c(n) have properties properties of ua^ε,b(n ), but they did not give or prove such properties. In this paper, properties of ua^ε,b,c( n ) which are similar to the theorem of Wolstenholme.
