The course focuses on basic notions and techniques in the field of Discrete Geometry, regarding point configurations and polytopes.
The techniques include algebraic, topological, geometric and combinatorial methods.
Details on the selected topics appear below.
Learning outcomes - On successful completion of this module, students should be able to:
Students will know fundamental results in Discrete Geometry and be able use algebraic, topological, geometric and combinatorial methods to address problems in the field.
The course will include also short student presentations.
Teaching arrangement and method of instruction:
Short pre-recorded lectures; live online discussions on the recorded material; short student presentations.
