"Coideal
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 sl_{n} and gl_{n} ).
I will explain how they are defined
and some of their basic properties.
In the second half, I
will discuss ongoing research about certain interesting
coideal subalgebras of Yangians and quantum affine algebras
associated to gl_{n} .
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

and at

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 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.
