摘要 ：
In this paper, we are concerned with the conservation of energy criterion of the weak solutions to the Navier-Stokes-Fourier equations on the torus allowing vacuum. We establish the energy conservation criteria via the gradient of velocity for the weak solutions of this system, which generalizes the corresponding recent energy conservation criteria in terms of the velocity obtained by Aoki and Iwabuchi in Aoki and Iwabuchi (2022). Moreover, sufficient conditions for weak solutions keeping the energy balance allowing vacuum are shown for the full Navier-Stokes equations.

摘要 ：
We consider non-isentropic Euler-Maxwell equations with relaxation times (small physical parameters) arising in the models of magnetized plasma and semiconductors. For smooth periodic initial data sufficiently close to constant steady-states, we prove the uniformly global existence of smooth solutions with respect to the parameter, and the solutions converge global-in-time to the solutions of the energy-transport equations in a slow time scaling as the relaxation time goes to zero. We also establish error estimates between the smooth periodic solutions of the non-isentropic Euler-Maxwell equations and those of energy-transport equations. The proof is based on stream function techniques and the classical energy method but with some new developments. (c) 2024 Elsevier Inc.

摘要 ：
This paper is concerned with the zero-relaxation limits for periodic smooth solutions of the non-isentropic Euler-Maxwell system in a three-dimensional torus prescribing the well/ill-prepared initial data. The non-isentropic Euler-Maxwell system can be reduced to a quasi-linear symmetric hyperbolic system of one order. By observing a special structure of the non-isentropic Euler-Maxwell system, we are able to decouple the system and develop a technique to achieve the a priori H-S estimates, which guarantees the limit for the non-isentropic Euler-Maxwell system as the relaxation time tau -> 0. We realize that the convergence rate of the temperature is the same as the other unknowns in the L-infinity(0, T-1; H-S), but the convergence rate of the temperature is slower than the velocity in L-2(0, T-1; H-S). The zero-relaxation limit presented here is the transport equation coupled with the drift-diffusion system. However, the limit of the isentropic Euler-Maxwell system is the classical drift-diffusion system. This shows the essential difference between the isentropic and non-isentropic Euler-Maxwell systems.

摘要 ：
In this paper we consider the initial value problem to the fractional compressible isentropic generalized Navier-Stokes equations for viscous fluids with one Levy diffusion process in which the viscosity term appeared in the fluid equations is described by the nonlocal fractional Laplace operator. We give one detailed spectrum analysis on a linearized operator and the decay law in time of the solution semigroup for the linearized fractional compressible isentropic generalized Navier-Stokes equations around a constant state by the Fourier analysis technique, which is shown that the order of the fractional derivatives plays a key role in the analysis so that the spectrum structure involved here is more complex than that of the classical compressible Navier-Stokes system. Based on this and the elaborate energy method, the global-in-time existence and one optimal decay rate in time of the smooth solution are obtained under the assumption that the initial data are given in a small neighborhood of a constant state.

摘要 ：
We consider the initial value problem to the fractional system of motions for compressible viscous fluids in this paper. We establish a local well-posedness theory for the system, as well as a global well-posedness theory for small initial data. We also show the large-time behavior of the solution, where solutions converge to a constant steady state exponentially in time.& COPY;2023 Elsevier Ltd. All rights reserved.

摘要 ：
The global well-posedness of a new class of initial-boundary value problem on incompressible MHD equations in the bounded domain with the smooth boundary is studied. The existence of a class of global weak solution to the initial boundary value problem for two/three-dimensional incompressible MHD equa-tion with the given pressure-velocity's relation boundary condition for the fluid field at the boundary and with one perfectly insulating boundary condition for the magnetic field at the boundary is obtained, and the global existence and uniqueness of the smooth solution to the corresponding problem in two-dimensional case for the smooth initial data is also established. The corresponding results are also extended to the two/three-dimensional incompressible MHD-Boussinesq equations with the density-velocity's rela-tion boundary condition for the density.(c) 2023 Elsevier Inc.

摘要 ：
In this paper, we consider the compressible Navier-Stokes-Maxwell equations with a non-constant background density in R-3. We first show the existence and uniqueness of the non-trivial equilibrium (steady-state) of the system when the background density is a small variation of certain constant state, then we prove the asymptotic stability of the steady-state once the initial perturbation around the steady-state is small. Furthermore, by establishing the time-decay estimates for the corresponding linearized homogeneous equations, we artfully derive the time-algebraic convergence rates. The proof is based on the time-weighted energy method but with some new developments on the weight settings.

摘要 ：
Global in time weak solutions to the alpha-model regularization for the three dimensional Euler-Poisson equations are considered in this paper. We prove the existence of global weak solutions to alpha-model regularization for the three dimension compressible Euler-Poisson equations by using the Fadeo-Galerkin method and the compactness arguments on the condition that the adiabatic constant satisfies gamma > 4/3.
