On the structure of Schubert modules and filtration by Schubert modules
(JAPANESE)
[ Abstract ]
One of the methods for studying Schubert polynomials is using
Schubert modules introduced by Kraskiewicz and Pragacz.
In this seminar I will talk about a new result on the structure of
Schubert modules, and give a criterion for a module to have a filtration by Schubert modules.
I will also talk about a problem concerning Schubert polynomials
which motivated this research.
