Hirzebruch genera of manifolds equipped with a Hamiltonian circle action
Theorem 1. The Todd genus of a manifold equipped with a symplectic circle action with isolated fixed points is either equal to zero and then the action is non-Hamiltonian, or equal to one and then the action is Hamiltonian. Any symplectic circle action on a manifold with the positive Todd genus is Hamiltonian. Proof. A symplectic circle action is Hamiltonian if and only if there is such a conne...
متن کاملLatent Semantic Indexing by Self-organizing Map
An important problem for the information retrieval from spoken documents is how to extract those relevant documents which are poorly decoded by the speech recognizer. In this paper we propose a stochastic index for the documents based on the Latent Semantic Analysis (LSA) of the decoded document contents. The original LSA approach uses Singular Value Decomposition to reduce the dimensionality o...
متن کاملHamiltonian Circle Actions with Minimal Fixed Sets
Consider an effective Hamiltonian circle action on a compact symplectic 2n-dimensional manifold (M, ω). Assume that the fixed set M 1 is minimal, in two senses: it has exactly two components, X and Y , and dim(X) + dim(Y ) = dim(M)− 2. We prove that the integral cohomology ring and Chern classes of M are isomorphic to either those of CP or to those of e G2(R), where e G2(R) denotes the Grassman...
متن کاملOn Circle Map Coupled Map Lattice
The circle map in one and two dimensions is studied. Both its stability and synchronization , using a bounded control and persistence, are discussed. This work is expected to be applicable in ecology where spatial effects are known to be important. Also, it will be relevant to systems where delay effects are not negligible.
متن کاملThe Moment Map Revisited
In this paper, we show that the notion of moment map for the Hamiltonian action of a Lie group on a symplectic manifold is a special case of a much more general notion. In particular, we show that one can associate a moment map to a family of Hamiltonian symplectomorphisms, and we prove that its image is characterized, as in the classical case, by a generalized “energy-period” relation.
