Complete intersection classification for binomial Macaulay dual generators
Determine, in terms of the exponents a_1,…,a_n and b_1,…,b_n, necessary and sufficient conditions under which the Artinian Gorenstein algebra A_F over a field of characteristic zero, with binomial Macaulay dual generator F = X_1^{a_1}⋯X_n^{a_n}(X_1^{b_1}⋯X_r^{b_r} − X_{r+1}^{b_{r+1}}⋯X_n^{b_n}) and 1 ≤ r ≤ n − 1, is a complete intersection.

In this last section we would like to formulate the open problems appearing in the introduction in the concrete case of AG algebras having binomial Macaulay dual generator. In the authors solved all the above problems in the codimension 3 case ($n=3$), while for arbitrary codimenson the problems are largely open, although partial results to some of them are given in previous sections of this paper.
