Weighted Inertia-Dissipation-Energy approach to doubly nonlinear wave equations

Goro Akagi, Verena Bögelein, Alice Marveggio +1

We discuss a variational approach to doubly nonlinear wave equations of the form $\rho u_{tt}+g(u_t)-\Delta u+f(u)=0$. This approach hinges on the minimization of a parameter-depende…
