متن کاملExtinction for Fast Diffusion Equations with Nonlinear Sources
We establish conditions for the extinction of solutions, in finite time, of the fast diffusion problem ut = ∆um +λup, 0 < m < 1, in a bounded domain of RN with N > 2. More precisely, we show that if p > m, the solution with small initial data vanishes in finite time, and if p < m, the maximal solution is positive for all t > 0. If p = m, then first eigenvalue of the Dirichlet problem plays a role.
متن کاملNumerical Solution of Nonlinear Diffusion with Finite Extinction Phenomenon
The implementation of the numerical method of W. Jäger and J. Kačur for solving the porous-medium type problems with strong absorption is disscussed. The computed numerical results concerning the extinction of the solution in finite time and the interface motions are presented.
متن کاملFinite Time Extinction for Solutions to Fast Diffusion Stochastic Porous Media Equations
We prove that the solutions to fast diffusion stochastic porous media equations have finite time extinction with strictly positive probability.
متن کاملScale-Invariant Extinction Time Estimates for Some Singular Diffusion Equations
We study three singular parabolic evolutions: the second-order total variation flow, the fourth-order total variation flow, and a fourth-order surface diffusion law. Each has the property that the solution becomes identically zero in finite time. We prove scale-invariant estimates for the extinction time, using a simple argument which combines an energy estimate with a suitable Sobolev-type ine...
