 ">Determining the complexity of Kazhdan-Lusztig varieties</a>\nby Laura Es
 cobar (Washington University in St. Louis) as part of SFU NT-AG seminar\n\
 n\nAbstract\nKazhdan-Lusztig varieties are defined by ideals generated by 
 certain minors of a matrix\, which are chosen by a combinatorial rule. The
 se varieties are of interest in commutative algebra and Schubert varieties
 . Each Kazhdan-Lusztig variety has a natural torus action from which one c
 an construct a cone. The complexity of this torus action can be computed f
 rom the dimension of the cone and\, in some sense\, indicates how close th
 e variety is to the toric variety of the cone. In joint work with Maria Do
 nten-Bury and Irem Portakal we address the problem of classifying which Ka
 zhdan-Lusztig varieties have a given complexity. We do so by utilizing the
  rich combinatorics of Kazhdan-Lusztig varieties.\n
