“…that over a Golod local ring that is not Gorenstein, every totally reflexive module is free. Another partial answer to Problem 1.30 is obtained by Yoshino [116], and by Christensen and Veliche [36]. The problem is also studied by Takahashi in [105].…”

“…In light of Proposition 4.4, we write the coefficients of the polynomial d(t) in terms of the invariants a i , q ij , b and a for some special cases and provide a uniform expression of the Poincaré series in these cases. (1 + t) n−1 1 − t − (a 1 − 1)t 2 − (a 3 − q 11 )t 3 + q 12 t 4 − bt 5 .…”

“…It follows that the kernel of the multiplication map φ 1 : A 1 ⊗ A 1 → A 2 is generated by a 2 1 − q 11 = 42 elements. We record the indices of basis elements of A 1 • A 1 by the set S = {(1, 2), (1,5), (1,6), (1, 7), (2, 3), (3,5), (4, 5)}.…”

“…Define N = T/M and let F and G be free resolutions of M and N , respectively. Since R is local with 3 = 0 we can assume that F i = R n and G i = R for all i ≥ 0, [8]. By applying the Horseshoe Lemma, we get the…”
