Weak solutions to a nonlinear variational wave equation and some related problems

Ping Zhang (2006)

Applications of Mathematics

Similarity:

In this paper we present some results on the global existence of weak solutions to a nonlinear variational wave equation and some related problems. We first introduce the main tools, the L p Young measure theory and related compactness results, in the first section. Then we use the L p Young measure theory to prove the global existence of dissipative weak solutions to the asymptotic equation of the nonlinear wave equation, and comment on its relation to Camassa-Holm equations in the second...

Coupled string-beam equations as a model of suspension bridges

Pavel Drábek, Herbert Leinfelder, Gabriela Tajčová (1999)

Applications of Mathematics

Similarity:

We consider nonlinearly coupled string-beam equations modelling time-periodic oscillations in suspension bridges. We prove the existence of a unique solution under suitable assumptions on certain parameters of the bridge.
