DESCRIPTION: In the theory of valid inequalities for integer point sets in 
 polyhedra\, the traditional\, finite-dimensional techniques of polyhedral c
 ombinatorics are complemented by infinite-dimensional methods\, the study o
 f cut-generating functions. I will give an introduction to these methods an
 d will explain their connection to lattice-free convex bodies. I will prese
 nt recent results involving inverse semigroups of partial maps\, obtained j
 ointly with Robert Hildebrand and Yuan Zhou\, and highlight some open quest
 ions regarding computability and complexity.
