Core Viewpoint - The project "Mathematical Research on Flow Transition Mechanisms," led by Wei Dongyi and Zhang Zhifei from Peking University, has been nominated for the 2025 National Natural Science Award in China [4]. Group 1: Project Details - The nomination for the National Natural Science Award was publicly announced by the Beijing Municipal Science and Technology Commission [3]. - The public notice period for the nomination is from June 18 to June 22, 2025 [3]. - The project focuses on significant problems in flow stability theory, including the optimal enhancement dissipation estimates for Kolmogorov flows and linear stability in high Reynolds number scenarios [5]. Group 2: Research Background - Wei Dongyi has a notable academic background, having entered Peking University in 2010, completing his undergraduate studies in 2014, and earning his PhD in 2017 [4]. - His research contributions include important advancements in the regularity of the three-dimensional Navier-Stokes equations and linear damping problems of two-dimensional incompressible Euler equations [4]. - Wei Dongyi's work has been recognized internationally, with discussions held at the renowned Bourbaki seminar regarding his research on Oseen vortex operators [4]. Group 3: Collaborations and Achievements - Wei Dongyi collaborated with assistant professor Yang Shiwu in 2020 to improve existing results on the long-term decay behavior of solutions to defocusing semi-linear wave equations [5]. - The innovative methods introduced by Wei and his collaborators have addressed several long-standing open problems in fluid mechanics, dating back to Reynolds' famous pipe flow experiment in 1883 [5].
