Abstract:
We deal with three families of evolutions problems modeling the interaction between acoustic waves and non-locally reacting surfaces. One family is constituted by problems derived in a Lagrangian framework, another family by problems derived in the Eulerian framework. In the talk, we show that they are equivalent with one between the two variants of the acoustic wave equation with acoustic boundary condition, which constitute the third family of problems. The results are connected with those in the talk given by the author in SS15, and are contained in two papers by the author, the first one in J. Evol. Eqs. (2024), the second one still in preparation.
