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

Date/Time/Room: Friday (9/30/2011) at 4:30 pm in 304 Pickard Hall

Speaker: Nicolas Guay,
Department of Mathematical and Statistical Sciences, University of Alberta, Canada.

"Co-ideal Subalgebras of Quantized Enveloping Algebras"

Abstract: The first half of the talk will be a brief introduction to quantum groups, especially to Yangians and quantized enveloping algebras of finite and affine Lie algebras (mainly for sln and gln ). I will explain how they are defined and some of their basic properties.

In the second half, I will discuss on-going research about certain interesting co-ideal subalgebras of Yangians and quantum affine algebras associated to gln . I will explain how they can be equivalently defined in terms of the reflection equation and how they are related to affine Hecke algebras of type BC.

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 304 is on the 3rd floor of PKH; turn right out of elevator on 3rd floor.

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.
