Abstract:
We construct solutions of the fast diffusion equation, which exist for all $t\in \mathbb {R}$ and are singular on the set $\Gamma (t)≔\{ \xi (s) ; -\infty <s \leq ct \}$, $c>0$, where $\xi \in C^3(\mathbb {R};\mathbb {R}^n)$, $n\geq 2$. We also give a precise description of the behavior of the solutions near $\Gamma (t)$.References
