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

pm in 311 Pickard Hall
Speaker: Associate
Prof. Anne Shepler, Department
of Mathematics, University of
North Texas.
"Groups Acting on
Algebras and PoincareBirkhoffWitt Theorems"
Abstract: We will discuss various
PoincareBirkhoffWitt 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 oneway 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 righthand 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.
