动力系统与分形几何讨论班——Harmonic Analysis of Mandelbrot Cascades

报告人：邱彦奇（国科大杭州高等研究院）时间：2024年7月2日 10:00-11:00地点：海纳苑2幢106室摘要：We will talk about the asymptotic decay of the Fourier coefficients of the Mandelbrot canonical cascade measure and more general cascade measures. Our method is to put the analysis of these Fourier series into the framework of vector-valued martingales, as well as to apply celebrated asymptotics of small ...

Dose the Belt and Road Initiative improve environmental quality of BRI countries?

报告人：罗鹏副研究员（深圳大学）时间：2024年6月22日（周六），上午10:00-11:00地点：海纳苑2幢202Abstract: Based on the panel data of 91 countries from 2009 to 2019, we used CO2 emissions per capita as a proxy variable to estimate environment and took BRI as a quasi-natural experiment. This paper applies difference-in-difference method and decoupling analysis to examine the effects ...

动力系统讨论班——Positivity of the Lyapunov exponent for potentials generated by Hyperbolic Transformations

报告人：张正鹤(University of California, Riverside)时间：2024年6月24日（周一），上午10:00-11:00地点：海纳苑2幢202Abstract: I will introduce a recent work in showing positivity of the Lyapunov exponent for Schrodinger operators with potentials generated by hyperbolic dynamics. Specifically, we showed that if the base dynamics is a subshift of finite type with an ergodic measure adm...

计算与应用讨论班——Delay-dependent elliptic reconstruction and optimal $L^\infty(L^2)$ a posteriori error estimates for fully discrete delay parabolic problems

报告人：王晚生（上海师范大学）时间：2024年6月14日15:00-17:00地点：海纳苑2幢202摘要：We derive optimal order a posteriori error estimates for fully discrete approximations of linear parabolic delay differential equations (PDDEs), in the L∞(L2)-norm. For the discretization in time we use Backward Euler and Crank-Nicolson methods, while for the space discretization we use standard conforming finite ...

计算与应用讨论班——Solving long-time nonlinear Schrodinger equation by a class of oscillation-relaxation integrators

报告人：王斌（西安交通大学）时间：2024年6月20日14:00地点：海纳苑2幢205摘要：In this talk, we are concerned with numerical integrators for the long time nonlinear Schrodinger equation. We propose a novel class of oscillation-relaxation integrators and study its convergence and energy conservation. The proposed integrators are shown to have improved uniform accuracy and nice near energy conservation...
