We give examples, investigate the geometry of foliations that arise from the definition of a Riemannian submersion, and find necessary sufficient conditions for total manifold to be a locally product Riemannian manifold. We also find necessary and sufficient conditions for a semi-invariant submersion to be totally geodesic. Moreover, we obtain a classification for semi-invariant submersions with totally umbilical fibers and show that such submersions put some restrictions on total manifolds.eninfo:eu-repo/semantics/openAccessRiemannian submersionHermitian manifoldanti-invariant Riemannian submersionsemi-invariant submersionArticle56117318310.4153/CMB-2011-144-82-s2.0-84856086935Q2WOS:000315421200017Q4
