Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Bloch's conjecture for symplectic autoequivalences on K3 surfaces
布洛赫 K3曲面 辛自等价
2023/4/13
Bloch's conjecture for a surface X over an algebraically closed field k states that every homologically trivial correspondence acts as 0 on the Albanese kernel. When X is a K3 surface, this conjecture...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Symplectic fillings of lens spaces and Seifert fibered spaces
透镜空间 塞弗特纤维空间 辛填充
2023/4/27
In this talk, we apply Menke's JSJ decomposition for symplectic fillings to several families of contact 3-manifolds. Among other results, we complete the classification up to orientation-preserving di...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Energy/dissipation-preserving split Birkhoffian multi-symplectic methods for Maxwell’s equations
麦克斯韦方程组 能量/耗散守恒分裂 Birkhofian 多辛方法
2023/5/18
We propose a novel kind of energy/dissipation-preserving split Birkhoffian multi-symplectic (S-BMS) methods for Maxwell's equations with dissipation terms. After investigating the non-autonomous and a...
2018哈密顿动力学与辛拓扑最新进展研讨会（Recent Advances in Hamiltonian Dynamics and Symplectic Topology Workshop）
2018 哈密顿动力学与辛拓扑最新进展 研讨会
2017/12/20
The study of Hamiltonian dynamical systems plays a fundamental role in many different contexts, both in pure and applied mathematics. Indeed, most of the physical laws ruling our everyday lives --the ...

The Seventh Advanced Seminar Symplectic Geometry and Topological Field Theory
2017/3/28
The topics of the 7th Advanced Seminar in Symplectic Geometry and Topological Field Theory are 1) Givental's quantization formula and Teleman's classification of semisimple cohomological field theory;...
Hill’s equations are an approximation that is useful in a number of areas of astrophysics including planetary rings and planetesimal disks. We derive a symplectic method for integrating Hill’sequation...
SCHUBERT POLYNOMIALS AND ARAKELOV THEORY OF SYMPLECTIC FLAG VARIETIES
SCHUBERT POLYNOMIALS ARAKELOV THEORY
2015/12/17
Let X = Sp2n/B the flag variety of the symplectic group. We
propose a theory of combinatorially explicit Schubert polynomials which represent the Schubert classes in the Borel presentation of t...
THE SYMPLECTIC PROPERTIES OF THE PGL(n; C)-GLUING EQUATIONS
GLUING EQUATIONS SYMPLECTIC PROPERTIES
2015/12/17
In [12] we studied PGL(n; C)-representations of a 3-manifold via a generalization of Thurston's gluing equations. Neumann has proved some symplectic properties of
Thurston's gluing equations that pla...

The Symplectic Geometry of Polygons in Euclidean Space.
A symplectic structure on a manifold is a closed nondegenerate exterior 2-
form. The most common type of symplectic structure arises on a complex
manifold as the imaginary part of a Hermitian metr...
