Blow-up and global existence results for fourth order hyperbolic equations

Yongda Wang, Politecnico di Milano

Aula seminari III piano

In this talk, we consider a class of fourth order hyperbolic equations, which is viewed as a mathematical model for suspension bridges. For this kind of problems, there exists a unique local solution. By the potential well theory, we show finite time blow-up and global existence results of the problems for different initial data.
