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…
