Talk & Lecture
Speaker: WU ShukunVenue: Room 204, building 2, Haina yuan, Zijingang campusAbstract: The local smoothing conjecture for wave equations was raised by Sogge, initially aiming to understand Stein's spherical maximal function. Because of its close connection to the Fourier transform of the surface measure of the sphere, the local smoothing conjecture has become a central topic in harmonic analysis...

Talk & Lecture
Speaker: Arnak DalalyanVenue: Room 1417, Administration Building, Zijingang CampusAbstract: Generative modeling aims to produce new random examples from an unknown target distribution, given access to a finite collection of examples. Among the leading approaches, denoising diffusion probabilistic models (DDPMs) construct such examples by mapping a Brownian motion via a diffusio...

14:00
Talk & Lecture
Speaker: Yafei LiangVenue: Room 426, School of Economics, Zijingang CampusAbstract: This study examines how large language models (LLMs) affect language barriers and disparities in publication outcomes and research impact for English-as-a-Foreign-Language (EFL) scholars. Using the release of ChatGPT-3.5 in November 2022 as a natural experiment, we analyze paper metadata from the Soc...

15:00
Talk & Lecture
Speaker: Kallol RayVenue: Room 203, Haina Building 2, Zijingang CampusAbstract: This work investigates both steady and unsteady nonlinear systems that couple the generalized convective Brinkman-Forchheimer model with a system of advection-diffusion equations, commonly referred to as double-diffusion equations. The existence and uniqueness of weak solutions to the governing equations...
