Abstract
The initial-value problem associated with multi-valued operators in Banach spaces is here reformulated as a minimization principle, extending results of Brezis-Ekeland, Nayroles and Fitzpatrick. At the focus there is the stability of these problems w.r.t.\ perturbations not only of data but also of operators; this is achieved via De Giorgi's -convergence w.r.t.\ a nonlinear topology of weak type. A notion of evolutionary -convergence of weak type is also introduced. These results are applied to quasilinear PDEs, including doubly-nonlinear flows.
