On the domain dependence of solutions to the two-phase Stefan problem

Eduard Feireisl, Hana Petzeltová (2000)

Applications of Mathematics

We prove that solutions to the two-phase Stefan problem defined on a sequence of spatial domains Ω n N converge to a solution of the same problem on a domain Ω where Ω is the limit of Ω n in the sense of Mosco. The corresponding free boundaries converge in the sense of Lebesgue measure on N .

On the eigenfunction expansion method for semilinear dissipative equations in bounded domains and the Kuramoto-Sivashinsky equation in a ball

V. V. Varlamov (2001)

Studia Mathematica

Presented herein is a method of constructing solutions of semilinear dissipative evolution equations in bounded domains. For small initial data this approach permits one to represent the solution in the form of an eigenfunction expansion series and to calculate the higher-order long-time asymptotics. It is applied to the spatially 3D Kuramoto-Sivashinsky equation in the unit ball B in the linearly stable case. A global-in-time mild solution is constructed in the space C ( [ 0 , ) , H s ( B ) ) , s < 2, and the uniqueness...

On the existence and regularity of the solutions to the incompressible Navier-Stokes equations in presence of mass diffusion

Rodolfo Salvi (2008)

Banach Center Publications

This paper is devoted to the study of the incompressible Navier-Stokes equations with mass diffusion in a bounded domain in R³ with C³ boundary. We prove the existence of weak solutions, in the large, and the behavior of the solutions as the diffusion parameter λ → 0. Moreover, the existence of L²-strong solution, in the small, and in the large for small data, is proved. Asymptotic regularity (the regularity after a finite period) of a weak solution is studied. Finally, using the Dore-Venni theory,...
