Riemannian submersions and slant submanifolds
(Institute of Mathematics (University of Debrecen), 2002)We study the relationship between slant submanifolds in both Complex and Contact Geometry through Riemannian submersions. ...

Rigidity of pseudo-isotropic immersions
(Elsevier, 2009-07)Several notions of isotropy of a (pseudo)Riemannian manifold have been introduced in the literature, in particular, the ...

Santilli autotopisms of partial groups
(Science Publishing Group, 2015-10)This paper deals with those partial groups that contain a given Santilli isotopism in their autotopism group. A classification of these autotopisms is explicitly determined for partial groups of order n ≤ 4.

Santilli's autotopism of associative partial quasigroups
(International Academic Press, 2007)In this paper, given an isotopism Θ ∈ In, we study some properties of the set SAPLS(Θ) of those partial Latin squares being the multiplication table of an associative partial quasigroup having Θ as a Santilli’s autotopism.

Sasaki-Einstein and paraSasaki-Einstein metrics from (κ,μ)-structures
(Elsevier, 2013-11)We prove that every contact metric (κ, µ)-space admits a canonical η-Einstein Sasakian or η-Einstein paraSasakian metric. ...

Structure on a slant submanifold of a contact manifold
(Indian National Science Academy, 2000-07)In this paper, we study the possibility of obtaining an induced contact metric structure on a slant submanifold of a contact metric manifold. We also give a characterization theorem for three-dimensional slant submanifolds.
