SUMMARY:Smooth Points on Positroid Varieties
LOCATION:H705
DESCRIPTION:Positroid varieties are subvarieties in the Grassmannian defined bycyclic r
 ank conditions and which are related to Schubertvarieties. They are also co
 nnected to N=4 supersymmetric Yang-Millstheory. In this talk, we will discu
 ss recent work by the authorstudying whether torus-fixed points on positroi
 d varieties aresmooth. This will involve looking at combinatorial diagrams 
 called"affine pipe dreams."
