Abstract
These are notes from lectures given at the Clay Institute Summer School on "Floer homology, gauge theory and low-dimensional topology" (Budapest, 2004). The first part describes as background some of the geometry of symplectic fibre bundles and their monodromy. The second part, overviewing joint work with Paul Seidel, applies these general ideas and Floer cohomology to certain fibre bundles that arise naturally in Lie theory. This constructs an invariant of oriented links in the three-sphere which is conjecturally equal to Khovanov's combinatorial homology theory.
