一个与中心三项式系数有关的同余式
A congruence related to central trinomial coefficients
摘要
Abstract
The central trinomial coefficient Tn denotes the coefficient of xn in the expansion of(1+x+x2)n.We prove a congruence related to the sums of the central trinomial coefficient and the central binomial coefficient,which was conjectured by Z.-W.Sun.关键词
