Giovedì 7 Giugno 2018, alle ore 15 precise, presso la sala conferenze dell’IMATI-CNR di Pavia, il
Dr. Robert Lasarzik, WIAS Berlino
terrà un seminario dal titolo:
Generalized solution concepts to the Ericksen-Leslie equations modeling liquid crystal flow
nell'ambito del Seminario di Matematica Applicata (IMATI-CNR e Dipartimento di Matematica, Pavia),
Al termine della conferenza sarà organizzato un piccolo rinfresco.
The Ericksen-Leslie equations are a system of nonlinear partial differential equations describing the flow of liquid crystals. This system is equipped with the non-convex Oseen-Frank energy leading to a nonlinear differential operator of second order that is non-monotone. Different partial answers to the question of well-posedness are presented in the form of different solvability concepts. The plethora of different solution concepts ranges from strong over weak and measure-valued solutions to dissipative solutions. A relative energy inequality holds for this system, which allows to deduce the weak-strong uniqueness property and investigate the long-time behavior.
