Speaker
Dr. Antonio Segatti
In this talk, I will introduce and analyse an elastic
surface energy recently introduced by G. Napoli and
L. Vergori to model thin films of nematic liquid crystals.
As it will be clear, the topology and the geometry of
the surface will play a fundamental role in understanding
the behavior of thin films of liquid crystals.
In particular, our results regards the existence of
minimizers, the existence of the gradient flow
of the energy and, in the case of an axisymmetric
toroidal particle, a detailed characterization of global and local minimizers.
This last item is supplemented with numerical experiments.
This is a joint work with M. Snarski (Brown) and M. Veneroni (Pavia).
