Let $u$ be the solution of the heat Cauchy problem, and let $\Omega$, $D$, $G$, and $\Gamma$ be the domains and boundary component appearing in Theorem. The theorem asserts, for…

Let $u$ be the solution of the heat Cauchy problem described in the paper, with $N=2$. Assume that there exists a function $a:(0,+\infty)\to(0,+\infty)$ such that $u(x,t)=a(t)$ for…
