Free Boundary Problems for Tumor Growth: a Viscosity Solutions Approach
The mathematical modeling of tumor growth leads to singular “stiff pressure law” limits for porous medium equations with a source term. Such asymptotic problems give rise to free boundaries, which, in the absence of active motion, are generalized Hele-Shaw flows. In this note we use viscosity solutions methods to study limits for porous medium-type equations with active motion. We prove the uni...
متن کاملOptimal Regularity of Viscosity Solutions of Fully Nonlinear Singular Equations and Their Limiting Free Boundary Problems
In the present paper, we start the journey of investigation into fully nonlinear elliptic singular equations of the form F (D2u, x) = βε(uε), where βε(uε) converges to the Dirac delta measure δ0. We show optimal regularity, uniform in ε, as well as H1 compactness for Bellman’s singular equations. We also provide a complete picture of limiting one-dimensional profiles. The study of further geome...
متن کاملOptimal Solutions for a Free Boundary Problem for Crystal Growth
We consider a free boundary problem modeling the growth/dissolution of a crystal in a radially symmetric setting. Existence of an optimal boundary control, minimizing a cost functional of a standardìntegral-quadratic' form, is already known and we here consider the characterization and computation of such an optimal control.
متن کاملExistence of multiple solutions for Sturm-Liouville boundary value problems
In this paper, based on variational methods and critical point theory, we guarantee the existence of infinitely many classical solutions for a two-point boundary value problem with fourth-order Sturm-Liouville equation; Some recent results are improved and by presenting one example, we ensure the applicability of our results.
متن کاملOn Approximate Stationary Radial Solutions for a Class of Boundary Value Problems Arising in Epitaxial Growth Theory
In this paper, we consider a non-self-adjoint, singular, nonlinear fourth order boundary value problem which arises in the theory of epitaxial growth. It is possible to reduce the fourth order equation to a singular boundary value problem of second order given by w''-1/r w'=w^2/(2r^2 )+1/2 λ r^2. The problem depends on the parameter λ and admits multiple solutions. Therefore, it is difficult to...
