On the Weak Lefschetz Property for Hilbert functions of almost complete intersections
Alfio Ragusa, Giuseppe Zappala
It is known that all complete intersection Artinian standard graded algebras of codimension 3 have the Weak Lefschetz Property. Unfortunately, this property does not continue to be…

A Structure Theorem and the Graded Betti Numbers for Almost Complete Intersections
Alfio Ragusa, Giuseppe Zappala
We provide a structure theorem for all almost complete intersection ideals of depth three in any Noetherian local ring. In particular, we find that the minimal generators are the p…
