We are concentrating on the nonlinear parabolic problem described by the equation in subject to zero Dirichlet conditions on the boundary ∂Ω, where Ω is a general domain that may be either bounded or unbounded. Here, , , , and we consider only nonnegative initial data. We have derived new conditions for global existence and blow up in finite time in terms of the behavior of the heat semigroup. Our results are particularly relevant when , as they align with Meier's findings in Meier (1990) [29]. When , our results provide new Fujita exponents.

The motion of a compressible inviscid radiative flow can be described by the radiative Euler equations, which consists of the Euler system coupled with a Poisson equation for the radiative heat flux through the energy equation. Although solutions of the compressible Euler system will generally develop singularity no matter how smooth and small the initial data are, it is believed that the radiation effect does imply some dissipative mechanism, which can guarantee the global regularity of the solutions of the radiative Euler equations at least for small initial data.
Such an expectation was rigorously justified for the one-dimensional case, as for the multidimensional case, to the best of our knowledge, no result was available up to now. The main purpose of this paper is to show that the initial-boundary value problem of such a radiative Euler equation in a three-dimensional bounded concentric annular domain does admit a unique global smooth radially symmetric solution provided that the initial data is sufficiently small.

We construct global weak solutions of the three dimensional incompressible Navier-Stokes equations in intermediate spaces between the space of uniformly locally square integrable functions and Herz-type spaces which involve weighted integrals centered at the origin. Our results bridge the existence theorems of Lemarié-Rieusset and of Bradshaw, Kukavica and Tsai. An application to eventual regularity is included which generalizes the prior work of Bradshaw, Kukavica and Tsai as well as Bradshaw, Kukavica and Ozanski.

We are concerned with the local well-posedness of three-dimensional incompressible charged fluids bounded by a free-surface. We show that the Euler-Poisson-Nernst-Planck system, wherein the pressure and electrostatic potential vanish along the free boundary, admits the existence of unique strong (in Sobolev spaces) solution in a short time interval. Our proof is founded on a nonlinear approximation system, chosen to preserve the geometric structure, with the aid of tangentially smoothing and Alinhac good unknowns in terms of boundary regularity, our priori estimates do not suffer from the derivative loss phenomenon.

We prove the existence and uniqueness of global, probabilistically strong, PDE-strong solutions of the 2D Stochastic Navier-Stokes Equation under Navier boundary conditions with a transport and stretching noise. We emphasise that the Navier boundary conditions enable energy estimates which appear to be prohibited for the usual no-slip condition. The importance of the Stochastic Advection by Lie Transport (SALT) structure, in comparison to a purely transport Stratonovich noise, is also highlighted in these estimates. In the particular cases of the free boundary condition and a convex domain, the inviscid limit exists and is a global, probabilistically weak, PDE-weak solution of the corresponding Stochastic Euler Equation with impermeable boundary condition.

We consider the three-dimensional compressible Navier–Stokes system with the Coriolis force and prove the long-time existence of a unique strong solution. More precisely, we show that for any and arbitrary large initial data in the scaling critical Besov spaces, the solution uniquely exists on provided that the speed of rotation is high and the Mach numbers are low enough. To the best of our knowledge, this paper is the first contribution to the well-posedness of the compressible Navier–Stokes system with the Coriolis force in the whole space . The key ingredient of our analysis is to establish the dispersive linear estimates despite a quite complicated structure of the linearized equation due to the anisotropy of the Coriolis force.

In this paper we generalize [3, Main Theorem] from actions of a single transformation to amenable group actions, which answers affirmatively the question raised in [3] by Burguet and the first-named author of the paper.

This paper studies an inverse problem for a multipopulation mean field game (MFG) system where the objective is to reconstruct the running and terminal cost functions of the system that couples the dynamics of different populations. We derive uniqueness results for the inverse problem with different types of available data. In particular, we show that it is possible to uniquely reconstruct some simplified forms of the cost functions from data measured only on a single population component under mild additional assumptions on the coupling mechanism. The proofs are based on the standard multilinearization technique that allows us to reduce the inverse problems into simplified forms.
