13:15 - 14:15	Anouk Brose University of California, Davis, US	Abstract The lattice diameter of a polytope measures the maximum number of collinear lattice points in a polytope, equivalently, the maximum number of lattice points in a one-dimensional section of a polytope. We study structural properties of the lattice diameter and show connections to the shortest vector problem and the lattice width of a polytope. Algorithmically, we give a fixed-dimension polynomial time algorithm that computes the lattice diameter of a rational polytope, and show that this problem is NP-hard when the dimension is non-fixed. Furthermore, we study how segments attaining the lattice diameter behave under dilation of the polytope and prove an Ehrhart-theory type result. This is joint work with G. Averkov, J.A. De Loera, G. Lopez-Campos, and A. Torres. DACO Seminar Lattice Diameters of Polytopes	HG G 19.1
