Formula in Quantum Schubert Calculus"
Murnaghan-Nakayama rule expresses the product of a Schur function
with a Newton power sum in the basis of Schur functions. As the
power sums generate the algebra of symmetric functions, the
Murnaghan-Nakayama rule is as fundamental as the Pieri rule.
Interesting, the resulting formulas from the Murnaghan-Nakayama
rule are significantly more compact than those from the Pieri
formula. In geometry, a Murnaghan-Nakayama formula computes the
intersection of Schubert cycles with tautological classes coming
from the Chern character.
this talk, I will discuss some background, and then some recent
work establishing Murnaghan-Nakayama rules for Schubert
polynomials and for quantum Schubert polynomials. This is joint
work with Morrison, Benedetti, Bergeron, Colmenarejo, and Saliola.
TO UTA AND PARKING INFORMATION
interactive map of UTA may be found at
, 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
- their southmost lot ) where the parking is free (but check the
signs), 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.
