Lagrangian submanifolds in product symplectic spaces

چکیده
We analyze the global structure of Lagrangian Grassmannian in the product symplectic space and investigate the local properties of generic symplectic relations. The cohomological symplectic invariant of discrete dynamical systems is generalized to the class of generalized canonical mappings. Lower bounds for the number of two-point and three-point symplectic invariants for billiard-type dynamical systems are found and several examples of symplectic correspondences encountered from physics are presented. © 2000 American Institute of Physics. @S0022-2488~00!01608-X#

On geometric properties of Lagrangian submanifolds in product symplectic spaces
We study the generic properties of symplectic relations. Local models of symplectic relations are described and the corresponding local symplectic invariants are derived. A stratification of the Lagrangian Grassmannian in the product symplectic space (N ×M, π∗ MωM − π∗ NωN ) is constructed and global homological properties of the strata are investigated.
متن کاملHamiltonian Actions and Homogeneous Lagrangian Submanifolds
We consider a connected symplectic manifold M acted on properly and in a Hamiltonian fashion by a connected Lie group G. Inspired to the recent paper [3], see also [12] and [24], we study Lagrangian orbits of Hamiltonian actions. The dimension of the moduli space of the Lagrangian orbits is given and we also describe under which condition a Lagrangian orbit is isolated. If M is a compact Kähler...
متن کاملHigher dimensional knot spaces for manifolds with vector cross product
Vector cross product structures on manifolds include symplectic, volume, G2and Spin (7)-structures. We show that their knot spaces have natural symplectic structures, and we relate instantons and branes in these manifolds with holomorphic disks and Lagrangian submanifolds in their knot spaces. For the complex case, the holomorphic volume form on a Calabi-Yau manifold de nes a complex vector cro...
متن کاملMaslov Class Rigidity for Lagrangian Submanifolds via Hofer’s Geometry
In this work, we establish new rigidity results for the Maslov class of Lagrangian submanifolds in large classes of closed and convex symplectic manifolds. Our main result establishes upper bounds for the minimal Maslov number of displaceable Lagrangian submanifolds which are product manifolds whose factors each admit a metric of negative sectional curvature. Such Lagrangian submanifolds exist ...
متن کاملDecomposable Representations and Lagrangian Submanifolds of Moduli Spaces Associated to Surface Groups
The importance of explicit examples of Lagrangian submanifolds of moduli spaces is revealed by papers such as [9, 25]: given a 3-manifold M with boundary ∂M = Σ, Dostoglou and Salamon use such examples to obtain a proof of the Atiyah-Floer conjecture relating the symplectic Floer homology of the representation space Hom(π1(Σ = ∂M), U)/U (associated to an explicit pair of Lagrangian submanifolds...
