Totally geodesic submanifolds of maximal rank in symmetric spaces
The authors classify all totally geodesic submanifolds of maximal rank in Riemannian symmetric spaces \(G/K\) of noncompact type. For the special case \(\text{rank}(G) = \text{rank}(K)\) this classification is already known from work by \textit{B.-Y. Chen} and \textit{T. Nagano} in [Duke Math. J. 45, 405--425 (1978; Zbl 0384.53024)].
