A relative Seidel morphism and the Albers map

Shengda Hu, Francois Lalonde

In this note, we introduce a relative (or Lagrangian) version of the Seidel homomorphism that assigns to each homotopy class of paths in Ham(M), starting at the identity and ending…

Cluster Homology

Octav Cornea, Francois Lalonde

We assign, to a Langrangian submanifold , a new homology which manages the bubbling of disks by means of auxiliary Morse data. This invariant of the Hamiltonian isotopy class of…

The homotopy type of the space of symplectic balls in above the critical value

Sylvia Anjos, Francois Lalonde

We compute in this note the full homotopy type of the space of symplectic embeddings of the standard ball (where is the capacity of the standard bal…

Length minimizing Hamiltonian paths for symplectically aspherical manifolds

Ely Kerman, Francois Lalonde

In this paper we consider the length minimizing properties of Hamiltonian paths generated by quasi-autonomous Hamiltonians on symplectically aspherical manifolds. Motivated by the…

Cohomological properties of ruled symplectic structures

Francois Lalonde, Dusa McDuff

This survey presents some recent results by the authors and Polterovich on the topological properties of ruled symplectic manifolds. The bundle M \to P \to B that is associated wit…

Symplectic Structures on Fiber Bundles

Francois Lalonde, Dusa McDuff

Let be a locally trivial fiber bundle over a connected CW complex with fiber equal to the closed symplectic manifold $(M,\om)$. Then is said to be a symplectic…
