Existence and regularity of weak solutions to a model for coarsening in molecular beam epitaxy 

Zhang, J.; Zhu, P. (2013-12-31)
Taking into account the occurrence of a zero of the surface diffusion current and the requirement of the Ehrlich-Schwoebel effect, Siegert et al. formulated a model of Langevin type that describes the growth of pyramid-like ...

The vanishing viscosity method for the sensitivity analysis of an optimal control problem of conservation laws in the presence of shocks 

Ou, Y.; Zhu, P. (2013-12-31)
In this article we study, by the vanishing viscosity method, the sensitivity analysis of an optimal control problem for 1-D scalar conservation laws in the presence of shocks. It is reduced to investigate the vanishing ...

Regularity of solutions to a model for solid-solid phase transitions driven by configurational forces 

Zhu, P. (2012-12-31)
In a previous work, we prove the existence of weak solutions to an initial-boundary value problem, with H 1(Ω) initial data, for a system of partial differential equations, which consists of the equations of linear elasticity ...

Solutions to a model with Neumann boundary conditions for phase transitions driven by configurational forces 

Alber, H.-D.; Zhu, P. (2011-12-31)
We study an initial boundary value problem of a model describing the evolution in time of diffusive phase interfaces in solid materials, in which martensitic phase transformations driven by configurational forces take ...

Spherically symmetric solutions to a model for phase transitions driven by configurational forces 

Ou, Y.; Zhu, P. (2011-12-31)
We prove the global-in-time existence of spherically symmetric solutions to an initial-boundary value problem for a system of partial differential equations, which consists of the equations of linear elasticity and a ...

Solvability via viscosity solutions for a model of phase transitions driven by configurational forces 

Zhu, P. (2011-12-31)
This article is concerned with an initial-boundary value problem for an elliptic-parabolic coupled system arising in martensitic phase transition theory of elastically deformable solid materials, e.g., steel. This model ...

Interface motion by interface diffusion driven by bulk energy: Justification of a diffusive interface model 

Alber, H.-D.; Zhu, P. (2011-12-31)
We construct an asymptotic solution of a system consisting of the partial differential equations of linear elasticity theory coupled with a degenerate parabolic equation, and show that when a regularity parameter tends to ...

Traveling waves to models of solid-solid phase transitions driven by configurational forces 

Zhu, P. (2011-12-31)
We study the existence of traveling/standing waves to models based on configurational forces. These models describe, respectively, structural phase transitions in solids, e.g., Shape memory alloys, and phase transitions ...

Stationary waves to viscous heat-conductive gases in half-space: Existence, stability and convergence rate 

Kawashima, S.; Nakamura, T.; Nishibata, S.; Zhu, P. (2010-12-31)
The main concern of this paper is to study large-time behavior of solutions to an ideal polytropic model of compressible viscous gases in one-dimensional half-space. We consider an outflow problem and obtain a convergence ...

Asymptotic stability of the stationary solution to an initial boundary value problem for the Mullins equation of fourth order 

Zhu, P. (2009-12-31)
In the present article we first study the existence of the stationary solution to an initial boundary value problem for the Mullins equation of fourth order, which was proposed by Mullins ["Two-dimensional motion of idealized ...
