Former Research Group

Combinatorial Algebraic Geometry

The main topics examined by the group were:

  1. toric geometry and its relations to phylogenetics and tensors
  2. secant varieties with a view towards tensor decompositions and tensor rank
  3. geometric approach to fast matrix multiplication
  4. combinatorial aspects of polytopes and relations to algebra
  5. application of local algebraic methods in topological problems
