Symplectomorphism Groups and Quantum Cohomology
نویسنده
چکیده
We discuss the question of what quantummethods (J-holomorphic curves and quantum homology) can tell us about the symplectomorphism group and its compact subgroups. After describing the rather complete information we now have about the case of the product of two 2-spheres, we describe some recent results of McDuff– Tolman concerning the symplectomorphism group of toric manifolds. This leads to an interpretation of the relations in the quantum cohomology ring of a symplectic toric manifold in terms of the Seidel elements of the generating circles of the torus action.

Symplectomorphism Groups and Almost Complex Structures
This paper studies groups of symplectomorphisms of ruled surfaces M for symplectic forms with varying cohomology class. This cohomology class is characterised by the ratio μ of the size of the base to that of the fiber. By considering appropriate spaces of almost complex structures, we investigate how the topological type of these groups changes as μ increases. If the base is a sphere, this cha...
متن کاملOn the Group of Diffeomorphisms Preserving a Locally Conformal Symplectic Structure
The automorphism group of a locally conformal symplectic structure is studied. It is shown that this group possesses essential features of the symplectomorphism group. By using a special type of cohomology the flux and Calabi homomorphisms are introduced. The main theorem states that the kernels of these homomorphisms are simple groups, for the precise statement see chapter 7. Some of the metho...
متن کاملSymplectic structures on fiber bundles
Let π : P → B be a locally trivial fiber bundle over a connected CW complex B with fiber equal to the closed symplectic manifold (M,ω). Then π is said to be a symplectic fiber bundle if its structural group is the group of symplectomorphisms Symp(M,ω), and is called Hamiltonian if this group may be reduced to the group Ham(M,ω) of Hamiltonian symplectomorphisms. In this paper, building on prior...
متن کاملCohomological Structure of the Mapping Class Group and Beyond
In this paper, we briefly review some of the known results concerning the cohomological structures of the mapping class group of surfaces, the outer automorphism group of free groups, the diffeomorphism group of surfaces as well as various subgroups of them such as the Torelli group, the IA outer automorphism group of free groups, the symplectomorphism group of surfaces. Based on these, we pres...
متن کاملOn the Homotopy of Symplectomorphism Groups of Homogeneous Spaces
Let O be a quantizable coadjoint orbit of a semisimple Lie group G. Under certain hypotheses we prove that #(π1(Ham(O))) ≥ #(Z(G)), where Ham(O) is the group of Hamiltonian symplectomorphisms of O. MSC 2000: 53D05, 57S05, 57T20
