Existence and qualitative theory for nonlinear accretive evolutions with Carathéodory forcing

Dieter Bothe

Let $A$ be $m$ -accretive in a real Banach space $X$ . Given closed sets $K (t) \subset X$ , we develop an existence theory for mild solutions of the constrained problem \[ u'(t)+Au(t)\…

The initial acceleration of a buoyant spherical bubble revisited

Dieter Bothe, Jun Liu, Pierre-Etienne Druet +3

An analytical derivation of the buoyancy-induced initial acceleration of a spherical gas bubble in a host liquid is presented. The theory makes no assumptions further than applying…
