An existence result and evolutionary $\Gamma$-convergence for perturbed gradient systems

Aras Bacho, Etienne Emmrich, Alexander Mielke

The initial-value problem for the perturbed gradient flow \[ B(t,u(t)) \in \partialΨ_{u(t)}(u'(t))+\partial \mathcal E_t(u(t)) \text{ for a.a. } t\in (0,T),\qquad u(0)=u_0 \] with…
