Positive-regularity norm inflation for the 3D hypodissipative Navier--Stokes equations
Guirong Tang, Shiyang Xiong
We prove same-space norm inflation for the three-dimensional hypodissipative Navier--Stokes equations with dissipation , . Let and \[ 0<s<1-2α+\f…

Zero-relaxation and vanishing-damping limits of pressureless Euler system
Guirong Tang
We are concerned with the one-dimensional pressureless Euler system with relaxation in the Radon measure space. As the relaxation time tends to zero, the entropy solution converges…

Relaxation limit of pressureless Euler-Poisson equations
GuiRong Tang
We investigate the relaxation problem for the one-dimensional pressureless Euler--Poisson equations with the initial density being a finite Radon measure. The entropy solution of t…
