Join-meet binomial algebras of distributive lattices
Barbara Betti, Takayuki Hibi
We investigate the defining ideal of the algebra over a field generated by the join-meet binomials coming from a finite distributive lattice. In the frame of algebras with straight…

F-threshold of determinantal rings
Barbara Betti, Alessio Moscariello, Francesco Romeo +1
In this paper, by using a combinatorial approach, we establish a new upper bound for the F-threshold $c^\mm(\mm)$ of determinantal rings generated by maximal minors. We prove that…
