Global dissipative solutions of the 3D Naiver-Stokes and MHD equations

Alexey Cheskidov, Zirong Zeng, Deng Zhang

For any divergence free initial data in , we prove the existence of infinitely many dissipative solutions to both the 3D Navier-Stokes and MHD equations, whose energy pr…

Non-Leray-Hopf solutions to 3D stochastic hyper-viscous Navier-stokes equations: beyond the Lions exponents

Wenping Cao, Zirong Zeng, Deng Zhang

We consider the 3D stochastic Navier-Stokes equations (NSE) on torus where the viscosity exponent can be larger than the Lions exponent 5/4. For arbitrarily prescribed divergence-f…

Existence and non-uniqueness of weak solutions with continuous energy to the 3D deterministic and stochastic Navier-Stokes equations

Alexey Cheskidov, Zirong Zeng, Deng Zhang

The continuity of the kinetic energy is an important property of incompressible viscous fluid flows. We show that for any prescribed finite energy divergence-free initial data ther…

Non-uniqueness for the hypo-viscous compressible Navier-Stokes equations

Yachun Li, Peng Qu, Zirong Zeng +1

We study the Cauchy problem for the isentropic hypo-viscous compressible Navier-Stokes equations (CNS) under general pressure laws in all dimensions . For all hypo-viscosi…

Sharp non-uniqueness for the 3D hyperdissipative Navier-Stokes equations: above the Lions exponent

Yachun Li, Peng Qu, Zirong Zeng +1

We study the 3D hyperdissipative Navier-Stokes equations on the torus, where the viscosity exponent can be larger than the Lions exponent . It is well-known that, due to L…

A Boundary Value Problem for a Class of Anisotropic Stochastic Degenerate Parabolic-Hyperbolic Equations

Hermano Frid, Yachun Li, Daniel Marroquin +2

We establish the well-posedness of an initial-boundary value problem of mixed type for a stochastic nonlinear parabolic-hyperbolic equation on a space domain $\cO=\cO'\X\cO''$ wher…
