Long-Time behavior of the tangential surface Navier-Stokes equation
Andrea Poiatti, Ulisse Stefanelli
We investigate the initial-value problem for the incompressible tangential Navier-Stokes equation with variable viscosity on a given two-dimensional surface without boundary. Exist…
The Weighted Inertia-Energy-Dissipation Principle
Ulisse Stefanelli
The Weighted Inertia-Energy-Dissipation (WIDE) principle is a global variational approach to nonlinear evolution equations of parabolic and hyperbolic type. The minimization of the…
Weighted Energy-Dissipation approach to semilinear gradient flows with state-dependent dissipation
Goro Akagi, Ulisse Stefanelli, Riccardo Voso
We investigate the Weighted Energy-Dissipation variational approach to semilinear gradient flows with state-dependent dissipation. A family of parameter-dependent functionals defin…
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 . This approach hinges on the minimization of a parameter-depende…
