报告摘要:
In this talk, I will first discuss two energy conservation criteria for very weak solutions, based on the control of the integrability of the straintensor. This is a new attempt at establishing energy conservation criteria by controlling the integrability of the strain tensor within the L^p framework. Next, I will present my col laborative work with Dr. Chol-Jun 0, where we prove a regularity criterion for weak solutions to the 3D incompressible Navier-Stokes equations in terms of the positive part of the intermediate eigenvalue of the strain matrix. Our result provides a positive answer to a problem posed by Miller in Arch. Ration. Mech. Anal., 2020, 235(1):99-139.
