Subspace arrangements as generalized star configurations
 

Stefan Tohaneanu

This talk revolves around  viewing  any projective subspace arrangement (i.e., a union of linear subspaces) as a generalized star configuration. One of the main advantages of this perspective is that we can design linear codes with prescribed codewords of minimum weight. If time permits, I will discuss  another application of this type of interpolation and we can answer some questions regarding the number of equations needed to define a subspace arrangement.
