Metroplex Algebraic Geometry, Algebra and Number Theory (AGANT) Seminar,
a joint venture of   UNT,   UTA   and   TCU

Date/Time/Room: Tuesday (05/28/2013) at 4:00 pm in 311 Pickard Hall

Speaker: Associate Prof. Anne Shepler,
Department of Mathematics, University of North Texas.


"Groups Acting on Algebras and Poincare-Birkhoff-Witt Theorems"

Abstract: We will discuss various Poincare-Birkhoff-Witt theorems and focus on algebras presented by generators and relations, especially those carrying group actions.  Using examples, we will touch on quantum polynomial rings, Weyl algebras, universal enveloping algebras, symmetric algebras, skew group algebras, graded affine Hecke algebras, symplectic reflection algebras, rational Cherednik algebras, and Koszul algebras and see how Hochschild cohomology can be used to prove PBW theorems.


A map of UTA may be found at http://www.uta.edu/maps/, and at http://www.uta.edu/maps/transportation. The former gives buildings and the latter gives parking lots; both are interactive.
Note that PKH is the triangular building in the 3 pm position in the former. Select Pickard Hall from the building selector. PKH is next to the ``garage'' & is on Nedderman Dr between Planatarium Place (aka College St) & West St. West St is one-way northbound between W Mitchell St and 3rd St. Parking is available in the nearby (East and SE of PKH) parking lots with a UTA permit (but many people park there late on Fridays with no permit). There are a few metered parking spots on the East side of Pickard Hall on West St. Visitor (free), & metered, parking is available by Davis Hall (marked DH in SW part of the submap). A parking garage (expensive) is nextdoor to PKH (use West St to get to it). Note that if heading south on Cooper, then no left turn is allowed to Nedderman Dr.
Note that PKH 311 is on the 3rd floor of PKH; turn LEFT out of elevator on 3rd floor to end of hall, left again towards the end of that hall, and 311 will be on your right-hand side.

Questions, etc on arrangements/directions should be sent to Dr Vancliff; if travelling from out of town, notify Dr Vancliff, as we will delay starting the talk for you if you are late.
