Let $(M, \omega)$ be a connected, compact symplectic manifold equipped with a Hamiltonian $G$ action, where $G$ is a connected compact Lie group. Let $\phi$ be the moment map. In \cite{L}, we proved the following result for $G=S^1$ action: as fundamental groups of topological ...
Homotopy groups of moduli spaces of representations The moduli space of representations of the fundamental group of a compact surface in a Lie group has a tremendously rich geometry relating to symplectic geometry, hyperk盲hler geometry, integrable systems, Teichm眉ller theory, etc. This ...

IntroductionLet X be a closed oriented surface of genus g ≥ 2 and let π = π 1 (X) be its fundamentalgroup. Let Sp(4,R) be the group of linear transformations of R 4 preserving its standardreal symplectic form. Consider the set X := Hom(π,Sp(4,R)) of group homomorphismsfrom...

摘要: Our main result is a characterization of open Seifert fibered 3-manifolds in terms of the fundamental group and large-scale geometric properties of a triangulation. As an application, we extend the Seifert Fiber Space Theorem and the Torus Theorem to a class of 3-orbifolds....

We conjecture that the result remains true if the fundamental group is infinite cyclic. We also formulate a generalization of the isometry-invariant geodesics problem, and a generalization of the celebrated Weinstein conjecture: on a closed contact manifold with a selected contact form, any strict ...

The fitness function value is a kind of important information in the search process, which can be more targeted according to the guidance of the fitness function value. Most existing meta-heuristic algorithms only use the fitness function value as an indicator to compare the current variables as ...
