On decomposing Betti tables and $O$-sequences [PDF]
arXiv, 2014 The Boij-S\"oderberg characterization decomposes a Betti table into a unique positive integral linear combination of pure diagrams. Given a module with a pure resolution, we describe explicit formulae for computing the decomposition of the Betti table of the module given the decomposition of the truncation of the Betti table, and vice versa.
