On pseudo-Einstein hypersurfaces of ℋ2n+s
(Indian National Science Academy, 1996-05)
In this paper, some properties of the geometry of pseudo-Einstein hypersurfaces of the S-manifold ℋ 2n+s are studied and a theorem concerning their principal curvatures is obtained.

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.

Un ejemplo de teoría de bordismo equivalente al PL-bordismo
(Academia de Ciencias Exactas, Físicas, Químicas y Naturales de Zaragoza, 1983)
In this paper we define the CPL-manifolds and we prove, by using a desingularization procedure, that these objects give a bordism theory which is equivalente to the PL-bordism. It's interesting to note that the famíly CPL ...

A historical perspective of the theory of isotopisms
(MDPI, 2018-08-03)
In the middle of the twentieth century, Albert and Bruck introduced the theory of isotopisms of non-associative algebras and quasigroups as a generalization of the classical theory of isomorphisms in order to study and ...

The L-sectional curvature of S-manifolds
(Düzce Üniversitesi, 2016-04)
We investigate L-sectional curvature of S-manifolds with respect to the Riemannian connection and to certain semi-symmetric metric and nonmetric connections naturally related with the structure, obtaining conditions for ...

Approximation axiomatique à la théorie du bordisme
(Université de Picardie Jules Verne, 1989)
This paper gives an axiomatical approximation to Bordism Theory. It proves those properties of a geometrical nature that a class of models must satisfy to develop a bordism theory in an abstract category.

Generalized (κ,μ)-space forms
(Springer, 2013-02)
Generalized (κ, µ)-space forms are introduced and studied. We examine in depth the contact metric case and present examples for all possible dimensions. We also analyse the trans-Sasakian case.

Ideas para enseñar: vidas de matemáticos que abrazaron la fe religiosa
(Federación Iberoamericana de Educación Matemática, 2014-03)
En este artículo se muestran las biografías de una serie de matemáticos, algunos de ellos muy conocidos por la obra científica que nos han legado, cuyas fuertes vocaciones religiosas los llevaron a ser además sacerdotes, ...
