On vanishing patterns in Betti tables of edge ideals Nevo, Eran
Description
Many important invariants of ideals in a polynomial ring can be read off from the locations of the zeros in
their corresponding Betti table, for example the regularity, projective dimension, etc. We consider two problems on Betti
tables of monomial ideals generated in degree 2 (edge ideals, after polarization): 1. Strand connectivity: can rows in the
Betti table have internal zeros? [Conca, Weildon] 2. Subadditivity: for ti the maximal j for which "i,j is nonzero, must
