Symmetry of bounded solutions to quasilinear elliptic equations in a half-space

Phuong Le

Let $u$ be a bounded positive solution to the problem $- Δ_{p} u = f (u)$ in $R_{+}^{N}$ with zero Dirichlet boundary condition, where $p > 1$ and $f$ is a locally Lipschitz continu…

Nonlocal dispersal equations in time-periodic media: principal spectral theory, bifurcation and asymptotic behaviors

Hoang-Hung Vo, Zhongwei Shen

This paper is devoted to the investigation of the following nonlocal dispersal equation $$ u_{t}(t,x)=\frac{D}{σ^m}\left[\int_ΩJ_σ(x-y)u(t,y)dy-u(t,x)\right]+f(t,x,u(t,x)), \quad t…

Continuity of solutions of a class of fractional equations

Duc Trong Dang, Erkan Nane, Dang Minh Nguyen +1

In practice many problems related to space/time fractional equations depend on fractional parameters. But these fractional parameters are not known a priori in modelling problems.…

Approximation of mild solutions of the linear and nonlinear elliptic equations

Nguyen Huy Tuan, Dang Duc Trong, Le Duc Thang +1

In this paper, we investigate the Cauchy problem for both linear and semi-linear elliptic equations. In general, the equations have the form \[ \frac{\partial^{2}}{\partial t^{2}}u…

The body force in a three-dimensional Lame' system: identification and regularization

Dang Duc Trong, Phan Thanh Nam, Phung Trong Thuc

Let a three-dimensional isotropic elastic body be described by the Lamé system with the body force of the form $F (x, t) = ϕ (t) f (x)$ , where $ϕ$ is known. We consider the problem of det…

On a nonlinear heat equation associated with Dirichlet -- Robin conditions

Le Thi Phuong Ngoc, Nguyen Van Y, Alain Pham Ngoc Dinh +1

This paper is devoted to the study of a nonlinear heat equation associated with Dirichlet-Robin conditions. At first, we use the Faedo -- Galerkin and the compactness method to pro…

Ice formation in the Arctic during summer: false-bottoms

Phan Thanh Nam, Alain Pham Ngoc Dinh, Pham Hoang Quan +1

The only source of ice formation in the Arctic during summer is a layer of ice called false-bottoms between an under-ice melt pond and the underlying ocean. Of interest is to give…

The regularity and exponential decay of solution for a linear wave equation associated with two-point boundary conditions

Le Xuan Truong, Le Thi Phuong Ngoc, Alain Pham Ngoc Dinh +1

This paper is concerned with the existence and the regularity of global solutions to the linear wave equation associated with two-point type boundary conditions. We also investigat…

The Riemann problem for the shallow water equations with discontinuous topography

Philippe G. LeFloch, Mai-Duc Thanh

We construct the solution of the Riemann problem for the shallow water equations with discontinuous topography. The system under consideration is non-strictly hyperbolic and does n…

Laguerre polynomials and the inverse Laplace transform using discrete data

Tran Ngoc Lien, Dang Duc Trong, Alain Pham Ngoc Dinh

We consider the problem of finding a function defined on $(0, \infty)$ from a countable set of values of its Laplace transform. The problem is severely ill-posed. We shall use the e…
