Surfaces of the nearly Kähler S3×S3 preserved by the almost product structure
Résumé
The product manifold S3×S3 is one of the only four homogeneous six-dimensional nearly Kähler manifolds. It also admits a canonical almost product structure P, which is compatible with the almost complex structure (see Bolton et al., Tôhoku Math. J. 67 (2015), 1–17, and Moruz and Vrancken, Publ. Inst. Math. 103 (2018), no. 117, 147–158). In this paper, we investigate and describe the two-dimensional surfaces of S3×S3 which are P-invariant.
