报告摘要
In this talk, we revisit the existence theory of weak solutions for the compressible Navier--Stokes system. We propose an approximation scheme that, instead of the classical regularization of the continuity equation (based on the viscosity approximation), employs a more direct truncation and regularization of nonlinear terms and the pressure. This scheme is compatible with the Kolmogorov compactness criterion for the density.
主讲人简介
Dr. Nilasis Chaudhuri is currently a postdoctoral researcher at the Faculty of Mathematics, Informatics, and Mechanics at the University of Warsaw in the workgroup of Prof. Piotr B. Mucha. He completed his PhD at the Technical University of Berlin under the supervision of Prof. Eduard Feireisl. He was also a postdoctoral research associate at Imperial College London in the working group of Prof. Ewelina Zatorska. His research interests lie in the analysis of partial differential equations arising in fluid dynamics, traffic flow, and collective behavior models.
