This thesis consists of two independent parts. In the rst part of the thesis, we develop a Riemann-Roch theory for sublattices of the root lattice An extending the work of Baker and Norine (Advances in Mathematics, 215(2): 766-788, 2007) and study questions that arise from this theory. Our theory is based on the study of critical points of a certain simplicial distance function on a lattice and establishes connections between the Riemann-Roch theory and the Voronoi diagrams of lattices under certain simplicial distance functions. In particular, we provide a new geometric approach for the study of the Laplacian of graphs. As a consequence, we obtain a geometric proof of the Riemann-Roch theorem for graphs and generalise the result to other s...
