Abstract: We explore the lifting question in the context of cut-generating functions. Most of the prior literature on lifting for cut-generating functions focuses on which cut-generating functions have the unique lifting property. Here we develop a general theory for under- standing how to do lifting for cut-generating functions which do not have the unique lifting property.

Keywords: cut-generating pair, lattice free set, lifting
