Minimal submanifolds via complex-valued eigenfunctions

S Gudmundsson, TJ Munn - The Journal of Geometric Analysis, 2024 - Springer
In this work we introduce a new method for manufacturing minimal submanifolds of
Riemannian manifolds of codimension two. For this we employ the so-called complex …

Minimal Submanifolds of the Classical Compact Riemannian Symmetric Spaces

JM Gegenfurtner - arXiv preprint arXiv:2406.11294, 2024 - arxiv.org
Minimal submanifolds constitute a central area within the realm of differential geometry, due
to their many applications in various branches of physics. In this thesis we will employ a …

Global eigenfamilies on compact manifolds

O Riedler, A Siffert - arXiv preprint arXiv:2401.17750, 2024 - arxiv.org
We study globally defined $(\lambda,\mu) $-eigenfamilies on compact Riemannian
manifolds. Among others, we provide (non-) existence results for such eigenfamilies …

Harmonic Morphisms and p-Harmonic Functions on the Classical Compact Symmetric Spaces via the Cartan Embedding

A Lindström - arXiv preprint arXiv:2402.15532, 2024 - arxiv.org
Given a symmetric triple $(G, K,\sigma) $ of compact type, with $ G^{\sigma}= K $, the well
known Cartan embedding $\hat {\Phi}: G/K\to G $ homothetically embeds the symmetric …

Polynomial harmonic morphisms and eigenfamilies on spheres

O Riedler - arXiv preprint arXiv:2310.19565, 2023 - arxiv.org
The eigenfamilies of Gudmundsson and Sakovich can be used to generate harmonic
morphisms, proper $ r $-harmonic maps, and minimal co-dimension $2 $ submanifolds. This …

Harmonic Riemannian submersions between Riemannian symmetric spaces of noncompact type

FE Burstall - Bulletin of the London Mathematical Society, 2024 - Wiley Online Library
We construct harmonic Riemannian submersions that are retractions from symmetric spaces
of noncompact type onto their rank‐one totally geodesic subspaces. Among the …
