Infinite families of harmonic self-maps of ellipsoids in all dimensions

Volker Branding, Anna Siffert

We prove that for given $k \in N$ , $k \geq 3$ , $d \in N$ and each $a \in R^{*}$ with \begin{align*} a^2<4d (d+k-2)(k-2)^{-2} \end{align*} the ellipsoid $E_a:=\{…

On p-harmonic self-maps of spheres

Volker Branding, Anna Siffert

In this manuscript we study rotationally $p$ -harmonic maps between spheres. We prove that for $p \in N$ given, there exist infinitely many $p$ -harmonic self-maps of $\mathbb…
