15 صفحه اولThe Maslov Index Revisited
Abs t r ac t . Let 7) be a Hermitian symmetric space of tube type, S its Shilov boundary and G the neutral component of the group of bi-holomorphic diffeomorphisms of 7). In the model situation 7) is the Siegel disc, S is the manifold of Lagrangian subspaces and G is the symplectic group. We introduce a notion of transversality for pairs of elements in S, and then study the action of G on the s...
متن کاملMaslov Index for Hamiltonian Systems
The aim of this article is to give an explicit formula for computing the Maslov index of the fundamental solutions of linear autonomous Hamiltonian systems in terms of the Conley-Zehnder index and the map time one flow.
متن کاملThe Maslov index for paths
Maslov’s famous index for a loop of Lagrangian subspaces was interpreted by Arnold [1] as an intersection number with an algebraic variety known as the Maslov cycle. Arnold’s general position arguments apply equally well to the case of a path of Lagrangian subspaces whose endpoints lie in the complement of the Maslov cycle. Our aim in this paper is to define a Maslov index for any path regardle...
متن کاملMaslov Index of Holomorphic Triangles
In this short article, we shall try to find an explicit formula for Maslov index of triangles joining intersections points of three half-dimensional tori in the symmetric product of a surface. The method will also yield a formula for the intersection number of such a triangle with the flat diagonal in the symmetric product.
