Title:A nonlinear variational wave equation
Seminar:Hyperbolic and Mixed Type PDEs Seminar
Speaker:Alberto Bressan, Penn State
Abstract:
The talk will focus on the nonlinear wave equation u_tt - c(u) (c(u) u_x)_x = 0 The first part will review some earlier results. In particular, by a change in the independent and dependent variables, the equation can be reformulated as a semiinear system, and solved by a standard fixed point argument. The second part will discuss open problems: structurally stable singularities, dissipative solutions, multi-dimensional radially symmetric solutions, uniqueness and continuous dependence on the initial data.
