Explicit harmonic self-maps of complex projective spaces

Abstract

We study $\mathrm{SU}(p+1)\times \mathrm{SU}(n-p)$-equivariant maps between complex projective spaces. For every $n,p\in \mathbb{N}$ with $0\le p<n$, we construct two explicit families of uncountable many harmonic self-maps of ${\mathbb{CP}}^n$, one given by holomorphic maps and the other by maps that are neither holomorphic nor antiholomorphic. We prove that each solution is equivariantly weakly stable and explicitly compute the equivariant spectrum for some specific maps in both families.
