2025.11.30 09:00--09:50 报告一: Some qualitative properties of mixed local and nonlocal equations

报告简介：In this talk, we will first introduce Liouville theorems for mixed local and nonlocal elliptic and parabolic equations with indefinite nonlinearties. Then we present monotonicity and one-dimensional symmetry of solutions to mixed local and nonlocal equations.

2025.11.30 10:00--10:50 报告二: Regularity Criteria for the 3D Axisymmetric Non-resistive MHD System in the Swirl Component of the Vorticity

报告简介：We study the regularity criteria of the 3D axisymmetric non-resistive MHD system with nonzero swirl. It is proved that if the swirl component of the vorticity belongs to some anisotropic Lorentz spaces or weighted Lebesgue spaces, then strong solutions of this system can be smoothly extended beyond the possible blow-up time T . In particular, no a priori assumptions on the magnetic field are imposed, and we also obtain a new result for the axisymmetric Navier–Stokes system.

2025.11.30 11:00--11:50 报告三: Complex system and PS-LSTM prediction of cryptocurrencies, stocks, bonds, exchange rates and commodities

报告简介：This report employs Phase Space Reconstruction and PS-LSTM to uncover nonlinear dynamics between Bitcoin and major financial assets. The enhanced accuracy of PS-LSTM highlights that cryptocurrencies are tightly coupled with systemic financial conditions rather than behaving as isolated assets.
