Conformal slant submersions

Yıl 2019, Cilt: 48 Sayı: 1, 28 - 44, 01.02.2019

Öz

As a generalization of conformal holomorphic submersions and conformal anti-invariant submersions, we introduce a new  conformal  submersion from almost Hermitian manifolds onto Riemannian manifolds, namely conformal slant submersions. We give examples and find necessary and sufficient conditions for such maps to be harmonic morphism. We also  investigate the geometry of foliations which are arisen from the definition of a conformal submersion and obtain a decomposition theorem on the total space of a conformal slant submersion. Moreover, we  find necessary and sufficient conditions of a conformal slant submersion to be totally geodesic.
