Details: Speaker: Dalton Bidleman Title: Intersection Structures on Secants of Grassmannians
Abstract: Restricted secant varieties of Grassmannians are constructed from sums of points corresponding to k-planes with the restriction that their intersection has a prescribed dimension. This talk shows how to calculate dimensions of restricted, cyclic, and path geometric secants of Grassmannians and relates them to the analogous question for secants of Grassmannians via an incidence variety construction. It also demonstrates example calculations in Macaulay 2 and points out ways to make these calculations more efficient.
