Seidel's long exact sequence on Calabi-Yau manifolds
In this paper, we generalize construction of Seidel's long exact sequence of
Lagrangian Floer cohomology to that of compact Lagrangian submanifolds with
vanishing Malsov class on general Calabi-Yau manifolds. We use the framework of
anchored Lagrangian submanifolds developed in \cite{fooo:anchor} and some
compactness theorem of \emph{smooth} -holomorphic sections of Lefschetz
Hamiltonian fibration for a generic choice of . The proof of the latter
compactness theorem involves a study of proper pseudoholomorphic curves in the
setting of noncompact symplectic manifolds with cylindrical ends.Comment: 59 pages, comments welcom
Floer homology and its continuity for non-compact Lagrangian submanifolds
We give a construction of the Floer homology of the pair of {\it non-compact}
Lagrangian submanifolds, which satisfies natural continuity property under the
Hamiltonian isotopy which moves the infinity but leaves the intersection set of
the pair compact. This construction uses the concept of Lagrangian cobordism
and certain singular Lagrangian submanifolds. We apply this construction to
conormal bundles (or varieties) in the cotangent bundle, and relate it to a
conjecture made by MacPherson on the intersection theory of the characteristic
Lagrangian cycles associated to the perverse sheaves constructible to a complex
stratification on the complex algebraic manifold.Comment: Submitted to the Proceedings for 7th Gokova Geometry-Topology

Chain level Floer theory and Hofer's geometry of the Hamiltonian diffeomorphism group
In this paper we first apply the chain level Floer theory to the study of
Hofer's geometry of Hamiltonian diffeomorphism group in the cases without
quantum contribution: we prove that any quasi-autonomous Hamiltonian path on
weakly exact symplectic manifolds or any autonomous Hamiltonian path on
arbitrary symplectic manifolds is length minimizing in its homotopy class with
fixed ends, as long as it has a fixed maximum and a fixed minimum which are not
over-twisted and all of its contractible periodic orbits of period less than
one are sufficiently -small. Next we give a construction of new invariant
norm of Viterbo's type on the Hamiltonian diffeomorphism group of arbitrary
compact symplectic manifolds.Comment: Section 6 concerning adic (or adiabadic) limit of Floer's moduli
