More about vanishing cycles and mutation
Paul Seidel
The paper continues the discussion of symplectic aspects of Picard-Lefschetz theory begun in "Vanishing cycles and mutation" (this archive). There we explained how to associate to…
Vanishing cycles and mutation
Paul Seidel
This is the writeup of a talk given at the European Congress of Mathematics, Barcelona. It considers Picard-Lefschetz theory from the Floer cohomology viewpoint.
Quivers, Floer cohomology, and braid group actions
Mikhail Khovanov, Paul Seidel
We consider the derived categories of modules over a certain family A_m of graded rings, and Floer cohomology of Lagrangian intersections in the symplectic manifolds which are the…
Braid group actions on derived categories of coherent sheaves
Paul Seidel, R. P. Thomas
This paper gives a construction of braid group actions on the derived category of coherent sheaves on a variety . The motivation for this is Kontsevich's homological mirror conj…
