Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Spectral instability of Electronic Euler-Poisson System
电子 Euler-Poisson系统 谱不稳定性
2023/12/11
The focus of this presentation is the spectral (in-)stability of periodic waves for the electronic Euler-Poisson system, a hydrodynamical model for understanding electron dynamics in plasmas. It is fo...
Inherited structures in deformations of Poisson pencils
Inherited structures deformations of Poisson pencils Mathematical Physics
2011/9/5
Abstract: In this paper with study some properties of bi-Hamiltonian deformations of Poisson pencils of hydrodynamic type. More specifically, we are interested in determining those structures of the f...
Essential variational Poisson cohomology
Essential variational Poisson cohomology Representation Theory
2011/7/27
Abstract: In our recent paper [DSK11] we computed the dimension of the variational Poisson cohomology for any quasiconstant coefficient matrix differential operator K of arbitrary order with invertibl...
Homotopical Poisson reduction of gauge theories
Homotopical Poisson reduction gauge theories Algebraic Geometry
2011/7/26
Abstract: The classical Poisson reduction of a given Lagrangian system with (local) gauge symmetries has to be done before its quantization. We propose here a coordinate free and self-contained mathem...

The Dirac Theory of Constraints, the Gotay-Nester Theory and Poisson Geometry
The Dirac Theory of Constraints the Gotay-Nester Theory Poisson Geometry
2011/7/26
Abstract: We present a study of the Dirac theory of constraints emphasizing the duality between the Poisson-algebraic and the geometric points of view, related respectively to the work of Dirac and of...
Photon Antibunching, Sub-Poisson Statistics and Cauchy-Bunyakovsky and Bell's Inequalities
Photon Antibunching Sub-Poisson Statistics Cauchy-Bunyakovsky Quantum Physics
2011/7/27
Abstract: We discuss some mathematical aspects of photon antibunching and sub-Poisson photon statistics. It is known that Bell's inequalities for entangled states can be reduced to the Cauchy-Bunyakov...
On Lie algebroids and Poisson algebras
Lie algebroids Poisson algebras faithful modules Differential Geometry
2011/7/27
Abstract: We introduce and study a class of Lie algebroids associated to faithful modules which is motivated by the notion of cotangent Lie algebroids of Poisson manifolds. We also give a classificati...
Exact Poisson pencils, $T$-structures and topological hierarchies
$T$-structures topological hierarchies evolutionary PDEs
2011/7/27
Abstract: We discuss, in the framework of Dubrovin-Zhang's perturbative approach to integrable evolutionary PDEs in 1+1 dimensions, the role of a special class of Poisson pencils, called exact Poisson...
Parallel FFT-based Poisson Solver for Isolated Three-dimensional Systems
Installation and Usage Solution Method
2011/8/29
We describe an implementation to solve Poisson’s equation for an isolated system on a unigrid mesh using FFTs. The method solves the equation globally on mesh blocks distributed across multiple proces...
Abstract: It is well known that the validity of the so called Lenard-Magri scheme of integrability of a bi-Hamiltonian PDE can be established if one has some precise information on the corresponding 1...
Poisson Yang-Baxter maps with binomial Lax matrices
Poisson Yang-Baxter maps binomial Lax matrices Quantum Algebra
2011/7/25
Abstract: A construction of multidimensional parametric Yang-Baxter maps is presented. The corresponding Lax matrices are the symplectic leaves of first degree matrix polynomials equipped with the Skl...
