Objective: The aim of GEOGRAL is to strengthen the bonds of the geometric theory of nonlinear PDEs (and, in particular, integrable systems and equations of Monge-Ampre type) with the geometry of Lagrangian Grassmannians and their submanifolds.

For example, from the usual representation of SLn(R) on C", one obtains actions on the parameter spaces of linear subspaces, that is, Grassmannians [Gr.
Drawn from lectures at a program held in 1999 in Taiwan's National Center for Theoretical Sciences, the topics include isothermic surfaces in terms of conformal geometry, Clifford algebras and integrable systems, introductions to homological geometry, isoparametric submanifolds and a Chevalley-type restriction theorem, a gauge-theoretic approach to harmonic maps and subspaces in Moduli spaces, and Schrodinger flows on Grassmannians.
This is the first contribution to the rigidity question for an important class of irreducible Hermitian symmetric spaces, the complex Grassmannians.
The five selections that make up the main body of the text are devoted to the Chern-Simons theory and knot invariants, tensor product algebras and Grassmannians and Khovanov homology, lectures on know homology, knot Floer homology, and knot homology and quantum curves.
Grassmannians are point-line spaces arising from projective spaces by considering the subspaces of a certain finite rank.
