Four end solutions of a free boundary problem
Web1 Free boundary problems 1.1 Introduction A free boundary problem occurs when the region in which the problem is to be solved is unknown in advance and must be found as part of the solution. We will describe a canonical free boundary problem known as the Stefan problem, which describes the ow of heat through a material where a phase … WebThey found that, unlike the Cauchy problem (where the so-called hair-trigger effect exists, that is, any positive solution of the Cauchy problem converges to 1 no matter how small …

We show multiple spreading phenomena ...
WebThis paper explores the free boundary problem with multistable nonlinearity and presents two cases for the solution’s spreading. The first one is four types of diffusion: big spreading, small spreading, small equilibrium and vanishing; the second one is a trichotomy result: big spreading, big equilibrium state and vanishing. Webevolution is regarded as a model problem for understanding moving free boundaries of parabolic nature. Roughly speaking, our focuses will be on: (i) construction of the solution; (ii) properties of the solution; and (iii) properties of the free boundary (regular points, singular points, features in the time evolutions, etc.).

WebMar 26, 2024 · This paper is devoted to classifying the dynamical behavior of solutions to a free boundary problem of a predator–prey model with a nonlocal reaction term. We investigate the spreading-vanishing dichotomy, that is, the asymptotic behavior of predator and prey species. Moreover, some criteria are also established for spreading and …

Another famous free-boundary problem is the obstacle problem, which bears close connections to the classical Poisson equation. The solutions of the differential equation satisfy a variational principle, that is to say they minimize the functional over all functions taking the value on the boundary. In the obstacle problem, we impose an additional constraint: we minimize the functional subject to the condition harvey norman manhattan ottomanWebMar 1, 2016 · This paper deals with a free boundary problem for diffusion equation with a certain class of bistable nonlinearity which allows two positive stable equilibrium states … puntsymmetrieWebfree boundary x= s(t), where the two conditions (1.4) and (1.5) are applied.
