Using BoijSoederberg theory to bound Betti numbers
Suppose that I is a homoeneous ideal of height c in a polynomial ring. Such ideals have at least c minimal generators, and that is about all we can say in this generality. If however we impose bounds on the regularity of the ideal then there are surprising constraints on the number of generators (and other Betti numbers). In this talk I'll describe how BoijSoederberg Theory gives rise to statements like this and how we use these methods to prove strong lower bounds for the total Betti number of modules with low regularity.
