a joint venture of   UNT,   UTA   and   TCU

Speaker: Dr. Natasha Rozhkovskaya, Associate Professor, Kansas State University 

"Explicit Constructions of Segal-Sugawara Vectors"

Abstract: The center of the affine vertex algebra at the critical level of a simple finite-dimensional Lie algebra is a commutative algebra whose structure was described by E. Feigin and E. Frenkel. In this talk, we will present the explicit formulas for Segal-Sugawara vectors associated with classical Lie algebras, found by A. Molev, and report on the case of the exceptional Lie algebra of type G2 (which is joint work with A. Molev and E. Ragoucy).


An interactive map of UTA may be found at http://www.uta.edu/maps/?panel=parking , which gives both buildings and parking lots (use the menu on the left of the map). Note that PKH is Pickard Hall and is on South Nedderman Drive.

If you think you will be able to come to the talk, and if you think you'll be wanting to park on campus, you could either try to park at a meter (a few next to Pickard Hall on West St and some on Nedderman Dr, West of Cooper St) or in free visitor parking (some available at Davis Hall - 5-min walk from Pickard Hall) or in the parking garage next to Pickard Hall (costs money) or in the college park district ( see https://www.uta.edu/collegeparkdistrict/parking/ - their southmost lot ) where the parking is free, but is approx 5-min walk from Pickard Hall.

Also, some changes in recent years:

  • Nedderman Dr to/from Planetarium Place from/to Cooper St is now closed to all traffic, and

  • the lot that used to be a student lot (between West St and Oak St) is now a faculty lot, and

  • the lot that used to be a faculty lot between West St and Cooper St is closed, and

  • there is handicapped parking in front of Pickard Hall with access from West St, and

  • note that West St (one-way) is accessible from Mitchell St only.

Since there is construction in downtown Arlington, the current recommended route from UNT is: get to I30 heading East, & follow directions from TCU given below. From TCU: east on I30, exit Cooper, South on Cooper, left (East) on W. Mitchell or right (West) on Nedderman, then use map.
