Three flavors of extremal Betti tables

arXiv:1207.5707 · doi:10.1007/978-1-4614-5292-8_4

Abstract

We discuss extremal Betti tables of resolutions in three different contexts. We begin over the graded polynomial ring, where extremal Betti tables correspond to pure resolutions. We then contrast this behavior with that of extremal Betti tables over regular local rings and over a bigraded ring.
