Symplectic homology and the Eilenberg-Steenrod axioms
We give a definition of symplectic homology for pairs of filled Liouville
cobordisms, and show that it satisfies analogues of the Eilenberg-Steenrod
axioms except for the dimension axiom. The resulting long exact sequence of a
pair generalizes various earlier long exact sequences such as the handle
attaching sequence, the Legendrian duality sequence, and the exact sequence
relating symplectic homology and Rabinowitz Floer homology. New consequences of
this framework include a Mayer-Vietoris exact sequence for symplectic homology,
invariance of Rabinowitz Floer homology under subcritical handle attachment,
and a new product on Rabinowitz Floer homology unifying the pair-of-pants
product on symplectic homology with a secondary coproduct on positive
symplectic homology.
In the appendix, joint with Peter Albers, we discuss obstructions to the
existence of certain Liouville cobordisms.Comment: v3: corrected Lemma 7.11. Various other minor modifications and

Symplectic hypersurfaces and transversality in Gromov-Witten theory
We use Donaldson hypersurfaces to construct pseudo-cycles which define
Gromov-Witten invariants for any symplectic manifold which agree with the
invariants in the cases where transversality could be achieved by perturbing
the almost complex structure.Comment: 53 pages, final versio

A note on mean curvature, Maslov class and symplectic area of Lagrangian immersions
In this note we prove a simple relation between the mean curvature form,
symplectic area, and the Maslov class of a Lagrangian immersion in a
K\"ahler-Einstein manifold. An immediate consequence is that in
K\"ahler-Einstein manifolds with positive scalar curvature, minimal Lagrangian
immersions are monotone.Comment: J. Symplectic Geom. vol 2 (2004), issue 2, 261-26
