This workshop will focus on border apolarity and the issues that arise with it.  We plan to explore:

  • the cactus variety
  • border apolarity in theory (for toric varieties)
  • basic deformation theory on zero dimensional schemes
  • representation theory/Borel fixed subspaces
  • implementation of border apolarity for tensors and polynomials
