Lyubeznik tables of Sr and CMr 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 CMr. Moreover we show that these results are sharp.
