        This is the first in a series of three courses on discrete geometry. The aim of the course is a skillful handling of discrete geometric structures including analysis and proof techniques. The material will be a selection of the following topics:
Basic structures in discrete geometry
 polyhedra and polyhedral complexes 
 configurations of points, hyperplanes, subspaces 
 Subdivisions and triangulations (including Delaunay and Voronoi) 
Polytope theory
 Representations and the theorem of Minkowski-Weyl  
 polarity, simple/simplicial polytopes, shellability 
 shellability, face lattices, f-vectors, Euler- and Dehn-Sommerville   
 graphs, diameters, Hirsch (ex-)conjecture 
Geometry of linear programming 
  
  linear programs, simplex algorithm, LP-duality 
Combinatorial geometry / Geometric combinatorics 
 
  Arrangements of points and lines, Sylvester-Gallai, Erdos-Szekeres,  
 Szemeredi--Trotter  
 Arrangements, zonotopes, zonotopal tilings, oriented matroids 
Examples, examples, examples   
 regular polytopes, centrally symmetric polytopes  
 extremal polytopes, cyclic/neighborly polytopes, stacked polytopes 
  combinatorial optimization and 0/1-polytopes 
For students with an interest in discrete mathematics and geometry, this is the starting point to specialize in discrete geometry. The topics addressed in the course supplement and deepen the understanding for discrete-geometric structures appearing in differential geometry, topology, combinatorics, andalgebraic geometry.
