Existence of solutions for the one-phase and the multi-layer
free-boundary problems with the p-laplacian operator
Idrissa Ly, Diaraf Seck
Abstract:
By considering the p-laplacian operator, we show the
existence of a solution to the exterior (resp interior) free
boundary problem with non constant Bernoulli free boundary
condition. In the second part of this article,
we study the existence of solutions to the two-layer shape
optimization problem. From a monotonicity result, we show
the existence of classical solutions to the two-layer Bernoulli
free-boundary problem with nonlinear joining conditions.
Also we extend the existence result to the multi-layer case.
