摘要： 

       The Navier–Stokes equations, Euler equations, nonlinear defocusing Schrödinger equation, wave equations, and Boltzmann equation are all important partial differential equations in physics. In the supercritical regime, the finite-time singularity formation for these equations is a highly challenging mathematical problem, among which the Millennium Prize Problem concerning finite-time singularity formation for the three-dimensional Navier–Stokes equations is the most renowned. This lecture will first present the work of Merle et al., who, by employing implosion solutions to the compressible Euler equations, constructed smooth blow-up solutions for the supercritical nonlinear defocusing Schrödinger equation and the three-dimensional compressible Navier–Stokes equations. Subsequently, we will introduce our recent progress on smooth blow-up solutions for the supercritical nonlinear defocusing wave equation and the monatomic compressible Navier–Stokes equations.
