Two-phase heat conductors with a stationary isothermic surface
Shigeru Sakaguchi
We consider a two-phase heat conductor in with consisting of a core and a shell with different constant conductivities. Suppose that, initially, the conduc…

Symmetry problems on stationary isothermic surfaces in Euclidean spaces
Shigeru Sakaguchi
Let be a smooth hypersurface properly embedded in with and consider its tubular neighborhood . We show that, if a heat flow over $\mathcal…
