Analysis of a multiphase free boundary problem [PDF]

open access: yesOpuscula Mathematica
In this paper, we investigate a free boundary problem relevant in several applications, such as tumor growth models. Our problem is expressed as an elliptic equation involving discontinuous nonlinearities in a specified domain with a moving boundary.

On the Optimal Control of the Free Boundary Problems for the Second Order Parabolic Equations. I.Well-posedness and Convergence of the Method of Lines [PDF]

open access: yes, 2012
We develop a new variational formulation of the inverse Stefan problem, where information on the heat flux on the fixed boundary is missing and must be found along with the temperature and free boundary.

Задача для параболического уравнения с двумя свободными границами

open access: yesVestnik KRAUNC: Fiziko-Matematičeskie Nauki, 2023
В данной работе рассматривается задача типа Стефана с двумя свободными границами для квазилинейного параболического уравнения в одномерном случае. Исследование нелинейных задач со свободными границами методом, основанным на построении априорных оценок ...

Free boundary problem for predator-prey model [PDF]

open access: yesE3S Web of Conferences, 2023
In this article, we study the behavior of two species evolving in a domain with a free boundary. This system mimics the spread of invasive or new predator species, in which free boundaries represent the expanding fronts of predator species and are ...

On the boundary form factor program [PDF]

open access: yes, 2006
Boundary form factor axioms are derived for the matrix elements of local boundary operators in integrable 1+1 dimensional boundary quantum field theories using the analyticity properties of correlators via the boundary reduction formula.

Regularity results for a quasilinear free boundary problem

open access: yesMathematical Modelling and Analysis, 2020
In this paper we prove local interior and boundary Lipschitz continuity of the solutions of a quasilinear free boundary problem. We also show that the free boundary is the union of graphs of lower semi-continuous functions.

Regularity in a one-phase free boundary problem for the fractional Laplacian [PDF]

open access: yes, 2011
For a one-phase free boundary problem involving a fractional Laplacian, we prove that "flat free boundaries" are $C^{1,\alpha}$. We recover the regularity results of Caffarelli for viscosity solutions of the classical Bernoulli-type free boundary problem

A free boundary focusing problem [PDF]

open access: yesProceedings of the American Mathematical Society, 1994
We consider a one-dimensional free boundary problem arising in combustion theory and establish that all solutions are asymptotically equal to a similarity solution which vanishes in a finite time.

Speed, Trajectory and Increment in the Number of Cells of Singly Flagellated Bacteria Swimming Close to Boundaries

open access: yesJournal of Biomechanical Science and Engineering, 2009
The influence of a rigid boundary and a free boundary on the motion of singly flagellated bacteria is experimentally investigated. The speed of backward swimming cells is faster near the rigid or free boundary than in the free space without boundary.
