Title:  Graded Shifts and the Shapes of Free Resolutions

Abstract:   Let I be a homogeneous ideal in a polynomial ring S = K[x_1,...,x_n] over a field K. Many of the properties of the homogeneous ideal associated to I can be determined from the minimal graded free resolution of I. In my talk I will discuss some progress on understanding the maximal graded shifts (i.e. degrees of syzygy modules) of ideals and modules over S. I will present some new restrictions on the maximal graded shifts of ideals, which can be thought of as restrictions on the shapes of the nonzero entries in the graded Betti table of an ideal.
