Solutions to a One-Dimensional Combustion-Type Free Boundary Problem via Maximal Regularity

Ken Furukawa, Yoshikazu Giga, Naoto Kajiwara

We study a one-dimensional free boundary problem arising in combustion theory, where the motion of the interface is governed by a prescribed Neumann boundary flux and a zero Dirich…

On dynamic stability of energetically stable equilibria of the Navier-Stokes-Korteweg flows

Yoshikazu Giga, Naoto Kajiwara, Kazuyuki Tsuda

We consider the Navier-Stokes-Korteweg equations in a bounded domain or a periodic cell. The pressure considered in this paper may not be monotone with respect to the density so th…

No formulation of a new phase for a free boundary problem in combustion theory

Ken Furukawa, Yoshikazu Giga, Naoto Kajiwara

We consider a free boundary problem for the heat equation with a given non-negative external heat source. On the free boundary, we impose the zero Dirichlet condition and the fixed…

Solution formula for generalized two-phase Stokes equations and its applications to maximal regularity; model problems

Naoto Kajiwara

In this paper we give a solution formula for the two-phase Stokes equations with and without surface tension and gravity in the whole space with flat interface. The solution formul…

Higher regularity for parabolic equations based on maximal L_p-L_q spaces

Naoto Kajiwara

In this paper we prove higher regularity for 2m-th order parabolic equations with general boundary conditions. This is a kind of maximal L_p-L_q regularity with differentiability,…

Strong time-periodic solutions to the bidomain equations with arbitrary large forces

Yoshikazu Giga, Naoto Kajiwara, Klaus Kress

We prove the existence of strong time-periodic solutions to the bidomain equations with arbitrary large forces. We construct weak time-periodic solutions by a Galerkin method combi…
