A Parabolic Free Boundary Problem with Bernoulli Type Condition on the Free Boundary

Consider the parabolic free boundary problem ∆u− ∂tu = 0 in {u > 0} , |∇u| = 1 on ∂{u > 0} . For a realistic class of solutions, containing for example all limits of the singular perturbation problem ∆uε − ∂tuε = βε(uε) as ε → 0, we prove that one-sided flatness of the free boundary implies regularity. In particular, we show that the topological free boundary ∂{u > 0} can be decomposed into an ...

A Free Boundary Problem for the Laplacian with Constant Bernoulli-type Boundary Condition

We study a free boundary problem for the Laplace operator, where we impose a Bernoulli-type boundary condition. We show that there exists a solution to this problem. We use A. Beurling’s technique, by defining two classes of suband supersolutions and a Perron argument. We try to generalize here a previous work of A. Henrot and H. Shahgholian. We extend these results in different directions.

Boundary Control of a Bernoulli Free Boundary Problem

We present a boundary optimal control approach for a Bernoulli free boundary problem. Our control objective consists in tracking a free boundary to an a priori given desired one. An appropriate cost functional is chosen for this purpose and its gradient is analytically derived. The resulting optimality conditions are discretized and the minimization problem is solved numerically by a steepest d...

THE ONE PHASE FREE BOUNDARY PROBLEM FOR THE p-LAPLACIAN WITH NON-CONSTANT BERNOULLI BOUNDARY CONDITION

Our objective, here, is to generalize our earlier results on the existence of classical convex solution to a free boundary problem with a Bernoullitype boundary gradient condition and with the p-Laplacian as the governing operator. The main theorems of this paper assert that the exterior and the interior free boundary problem with a Bernoulli law, i.e. with a prescribed pressure a(x) on the “fr...

On Bernoulli Boundary Value Problem

We consider the boundary value problem:    x (m) (t) = f (t, x(t)), a ≤ t ≤ b, m > 1 x(a) = β 0 ∆x (k) ≡ x (k) (b) − x (k) (a) = β k+1 , continuous at least in the interior of the domain of interest. We give a constructive proof of the existence and uniqueness of the solution, under certain conditions, by Picard's iteration. Moreover Newton's iteration method is considered for the numerical ...
