Computing Schubrt Problems

This is a series of  informal discussions about Grassmannians and flag
varieties, with the goal of  describing both how to represent Schubert
problems on  a computer  and some goals  of this  computational study.
This includes reality, Galois groups,  and new work around the Wronski
map.

Discussion 1:  28 January 2025

Defined  the Grassmannian  and  its  projective embedding.   Explained
Stiefel  coordinates  and  began  to  discuss  it  decomposition  into
Schubert cells.

Discussion 2:  4 February 2025

Schubert decomposition and Schubert varieties for the Grassmannian.
