Betti tables of graded systems of ideals
MATX 1102
Mon 27 Mar 2017, 3:00pm-4:00pm

Abstract

Several patterns emerge in collections of Betti tables associated to the powers of a fixed ideal.  For example, Wheildon and others demonstrated that the shapes of the nonzero entires of these tables eventually stabilize when the fixed ideal has generators of the same degree.  In this talk, I will discuss patterns in the graded Betti numbers of these and other graded systems of ideals.  In particular, I will describe ways in which the Betti tables may stabilize, and how different types of stabilization are reflected in the corresponding Boij-Soederberg decompositions.
