h-v-semi-slant submersions from almost quaternionic Hermitian manifolds (Q2812591)

This paper deals with a new class of Riemannian submersions, called (almost) h-v-semi-slant submersions, from almost quaternionic Hermitian manifolds onto Riemannian manifolds. The author characterizes the integrability of the canonical distributions involved in the definition and investigates the geometry of foliations and a decomposition theorem. Moreover, an inequality for a h-v-semi-slant submersion, involving the squared mean curvature, scalar curvature and the h-v-semi-slant angle, is stated in the last part of the paper. Finally, some examples are given.
