Title:Damping for Fractional Wave Equations

Speaker: Jian Wang(University of north carolina)

Time: July 7,16:00-17:00



Motivated by numerically modeling surface waves for inviscid Euler equations, we analyze linear models for damped waterwaves and establish decay properties for the energy for sufficiently regular initial configurations.Our findings give the explicit decay rates for the energy, but do not address reflection/transmission of waves at the interface of the damping. Still for a subset of the models considered, this represents the first result proving the decay of the energy of the surface wave models. Joint work with Thomas Alazard and Jeremy Marzuola.
