@MartinSleziak Both jordan-curves and knots are gone. mathoverflow.net/posts/362018/revisions As far as I can tell, this was the first occurrence of jordan-curves.

Consider the free boundary problem $$ \min\{u_t - u_{xx} -1, u \} = 0 \qquad \text{ in } (0,T)\times (-1,1) \\ u(0,\cdot) = 0 \qquad \text{ in } (-1,1)\\ u(\cdot, -1) = u(\cdot, 1) = 0 \qquad \text{ in } (0,T) $$ Can we obtain an explicit solution for it?

I want to solve a parabolic obstacle problem, written as a variational inequality: For almost all $t\in [0,T]$ \begin{align*} \langle u'(t), v - u(t)\rangle +a(u(t),v-u(t)) \geq \langle f(t),v-u(t)\rangle \quad \forall v \in K \end{align*} with $K = \{v \in H^1_0(\Omega) ~\vert ~ v \geq \chi ~ ...
