计算与应用讨论班

题目:计算与应用讨论班-Geometric Quasi-Linearization (GQL) for Bound-Preserving Schemes报告人：吴开亮（南方科技大学）时间：2023年10月20日下午4:00-5:00地点：海纳苑2幢202摘要: Solutions to many partial differential equations satisfy certain bounds or constraints. For example, the density and pressure are positive for equations of fluid dynamics, and in the relativistic case the fluid velocity is up...

Computational methods for the dynamics of the nonlinear Schroedinger/Gross-Pitaevskii equations

报告人：包维柱教授（新加坡国立大学）时间：10月19日10:00-11:00地点：海纳苑2幢204室摘要：In this talk, I begin wtih the (nonlinear) Schroedinger/Gross-Pitaevskii equations (NLSE/GPE) for modeling Bose-Einstein condensation (BEC), nonlinear optics, quantum physics and chemistry, etc., and review some dynamical properties of NLSE/GPE including conserved quantities, dispersion relation,center-of-mass d...
