Description

whether it is true the function tMacaulayExpansion gives the $i$-th shifted Macaulay expansion of $a$. Given four positive integers $(a,n,d,t)$ the $d$-th shifted t-Macaulay expansion is a sum of binomials: $\binom{a_d}{d+1} + \binom{a_{d-1}}{d} + \cdots + \binom{a_j}{j+1}.$

Examples:

i1 : tMacaulayExpansion(50,12,2,1,Shift=>true) o1 = {{10, 3}, {5, 2}} o1 : List
