A globally smooth solution to the relativistic string equation
Jinhua Wang, Changhua Wei
We prove the global existence of smooth solution to the relativistic string equation in a class of data that is not small. Our solution admits the feature that the right-travelling…
Future stability of the FLRW spacetime for a large class of perfect fluids
Chao Liu, Changhua Wei
We establish the future non-linear stability of Friedmann-Lema\^ıtre-Robertson-Walker (FLRW) solutions to the Einstein-Euler equations of the universe filled with a large class of…
Global existence of smooth solution to relativistic membrane equation with large data
Jinhua Wang, Changhua Wei
This paper is concerned with the Cauchy problem for the relativistic membrane equation (RME) embedded in with . We show that the RME with a class of la…
Boundedness of the total energy of relativistic membranes evolving in a curved spacetime
Philippe G. LeFloch, Changhua Wei
We establish a global existence theory for the equation governing the evolution of a relativistic membrane in a (possibly curved) Lorentzian manifold, when the spacetime metric is…
The global nonlinear stability of self-gravitating irrotational Chaplygin fluids in a FRW geometry
Philippe G. LeFloch, Changhua Wei
We analyze the global nonlinear stability of FRW (Friedmann-Robertson-Walker) spacetimes in presence of an irrotational perfect fluid. We assume that the fluid is governed by the s…
Completely linear degeneracy for quasilinear hyperbolic systems in several space variables
De-Xing Kong, Chang-Hua Wei
In this paper, we introduce the concept of completely linear degeneracy for quasilinear hyperbolic systems in several space variables, and then get an interesting property for mult…
Formation and propagation of singularities in one-dimensional Chaplygin gas
De-Xing Kong, Changhua Wei
In this paper, we investigate the formation and propagation of singularities for the system for one-dimensional Chaplygin gas, which is described by a quasilinear hyperbolic system…
Formation of singularities in one-dimensional Chaplygin gas
De-Xing Kong, Changhua Wei, Qiang Zhang
In this paper we investigate the formation and propagation of singularities for the system for one-dimensional Chaplygin gas. In particular, under suitable assumptions we construct…
Lifespan of smooth solutions for timelike extremal surface equation in de Sitter spacetime
De-Xing Kong, Chang-Hua Wei
In this paper, we study the generalized timelike extremal surface equation in the de Sitter spacetime, which plays an important role in both mathematics and physics. Under the assu…
