The Lyubeznik table of Sr and CMt rings
We describe the shape of the Lyubeznik table of either rings in positive characteristic or Stanley–Reisner rings in any characteristic when they satisfy Serre’s condition Sr or they are Cohen–Macaulay in a given codimension, condition denoted by CalebMoretonr. We show that these results are sharp....
