Tim van Beeck (Univ. Göttingen)

terrà un seminario dal titolo:Analysis and approximation of the nematic
Helmholtz-Korteweg equation.
Abstract: In this talk, we consider the nematic Helmholtz-Korteweg
equation, which has been derived recently to model the propagation of
acoustic waves in a nematic-Korteweg fluid. We show well-posedness of the
continuous problem with sound soft, sound hard, and impedance boundary
conditions by employing (weak) T-coercivity arguments. Afterwards, we
consider a C1 conforming FEM approximation, where we impose the boundary
conditions through Nitsche’s method.
This is joint work with P. E. Farrell and U. Zerbinati.
