Minimal free resolutions for homogeneous ideals with Betti numbers
Alfio Ragusa, Giuseppe Zappalà
We investigate the standard generalized Gorenstein algebras of homological dimension three, giving a structure theorem for their resolutions. Moreover in many cases we are able to…

Lefschetz properties for Artinian Gorenstein algebras presented by quadrics
Rodrigo Gondim, Giuseppe Zappalà
We introduce a family of standard bigraded binomial Artinian Gorenstein algebras, whose combinatoric structure characterizes the ones presented by quadrics. These algebras provide,…
