Trudinger's Parabolic Equation

Peter Lindqvist, Mikko Parviainen, Saara Sarsa

We study the uniqueness of non-negative solutions of the equation \begin{align*} \partial_t\left(|u|^{p-2}u\right)\,=\, \operatorname{div}(|\nabla u|^{p-2}\nabla u). \end{align*} B…

Duality for the gradient of a $p$ -harmonic function and the existence of gradient curves

Sylvester Eriksson-Bique, Saara Sarsa

Every convex optimization problem has a dual problem. The $p$ -Dirichlet problem in metric measure spaces is an optimization problem whose solutions are $p$ -harmonic functions. What…
