Clairaut slant submersion from almost Hermitian manifolds [PDF]

open access: yesMathematica Moravica
Our main aim is to introduce Clairaut slant submersions in complex geometry. We give the notion of Clairaut slant submersions from almost Hermitian manifolds onto Riemannian manifold in this article. We obtain some basic results on discussed submersions.

The sphere and the cut locus at a tangency point in two-dimensional almost-Riemannian geometry

open access: yes, 2010
We study the tangential case in 2-dimensional almost-Riemannian geometry. We analyse the connection with the Martinet case in sub-Riemannian geometry. We compute estimations of the exponential map which allow us to describe the conjugate locus and the ...

Geometric aspects of transversal Killing spinors on Riemannian flows [PDF]

open access: yesarXiv, 2008
We study a Killing spinor type equation on spin Riemannian flows. We prove integrability conditions and partially classify those Riemannian flows $M$ carrying non-trivial solutions to that equation in case $M$ is a local Riemannian product, a Sasakian manifold or 3-dimensional.

Biharmonic Riemannian maps [PDF]

open access: yesarXiv, 2010
We give necessary and sufficient conditions for Riemannian maps to be biharmonic. We also define pseudo umbilical Riemannian maps as a generalization of pseudo-umbilical submanifolds and show that such Riemannian maps put some restrictions on the base manifolds.
