Jet Geometrical Objects Depending on a Relativistic Time

open access: yes, 2008
In this paper we study a collection of jet geometrical concepts, we refer to d-tensors, relativistic time dependent semisprays, harmonic curves and nonlinear connections on the 1-jet space J1(R;M), necessary to the construction of a Miron's-like ...

Harmonic morphisms from the Grassmannians and their non-compact duals

open access: yes, 2006
In this paper we give a unified framework for the construction of complex valued harmonic morphisms from the real, complex and quaternionic Grassmannians and their non-compact duals.

Harmonic morphisms from the classical compact semisimple Lie groups

open access: yes, 2007
In this paper we introduce a new method for manufacturing harmonic morphisms from semi-Riemannian manifolds. This is employed to yield a variety of new examples from the compact Lie groups SO(n), SU(n) and Sp(n) equipped with their standard Riemannian ...

Slant Riemannian maps from almost Hermitian manifolds

open access: yes, 2012
As a generalization of holomorphic submersions, anti-invariant submersions and slant submersions, we introduce slant Riemannian maps from almost Hermitian manifolds to Riemannian manifolds.
