摘    要:对于整数k,θ≥3,β≥1,称k个元素集合S为(k;β,θ)0自由集,如果S的最小元素为0且它没有互不相同的元素aij∈S(1≤j≤θ使得∑j=1θ-1aij=βa成立,S的最大元素记为max(S).反平均数定义为λ(k;β,θ)=min{max(S):S是(k;β,θ)0自由集}.给出反平均数λ(k;β,θ)的2个界.

关 键 词:反平均数  对偶集合  优美集

Abstract:For integers k,θ≥3 and,β≥1,we say a k-set S as a(k;β,θ)0-free set if thesmallest number of S is 0,and S does not contain distinct elements aij∈S(1≤j≤9) suchthat∑j=1θ=1aij =βα.The maximum number of S is denoted as max(S).The generalizedantiaverage number is defined asλ(k;β,θ) = min{max(S):S is(k;β,θ)0-free set}.Twobounds of antiaverage numbers X(k;β,θ) are shown here.
Keywords:antiaverage set  dual set  graceful sets
