T. Ikeda, Overview of the workshop,

Let us start reviewing some aspects of the Grassmannian and its Schubert subvarieties. How we understand the Schubert conditions, how we can resolve the singularity of the Schubert varieties, and how these considerations lead to the determinantal formula fo the Schubert classes. We will also discuss how the results are related to representation theory. Several talks of this workshop will be variations on theme of the Grassmannian, the prototype of our discussions.
