Global solvability for the heat equations in two half spaces and an interface

Hajime Koba

This paper considers the existence of a global-in-time strong solution to the heat equations in the two half spaces $R_{+}^{3} (= R^{2} \times (0, \infty))$ , $\mathbb{R}^3…

On the Poisson Equation on a Surface with a boundary condition in co-normal direction

Hajime Koba, Yuki Wakasugi

This paper considers the existence of weak and strong solutions to the Poisson equation on a surface with a boundary condition in co-normal direction. We apply the Lax-Milgram theo…
