Lagrangian submanifolds in complex space forms satisfying an improved equality involving δ(2,2)
(Institutum Mathematicum Universitatis Debreceniesis, 2013)
It was proved in [8, 9] that every Lagrangian submanifold M of a complex space form M˜ 5 (4c) of constant holomorphic sectional curvature 4c satisfies the following optimal inequality: δ(2, 2) ≤ 25 4 H 2 + 8c, (A) where ...

The curvature tensor of almost cosymplectic and almost Kenmotsu ( κ, μ, ν ) -space
(Springer, 2013-08)
We study the Riemann curvature tensor of (κ, µ, ν)-spaces when they have almost cosymplectic and almost Kenmotsu structures, giving its writing explicitly. This leads to the definition and study of a natural generalisation of ...

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.

Relating the Freiheitssatz to the asymptotic behavior of a group
(European Mathematical Society, 2013)
We are concerned with the implications of the Freiheitssatz property for certain group presentations in terms of proper homotopy invariants of the underlying group, by describing its fundamental pro-group. A finitely ...

A historical review of the classifications of Lie algebras
(Unión Matemática Argentina, 2013)
The problem of Lie algebras’ classification, in their different varieties, has been dealt with by theory researchers since the early 20th century. This problem has an intrinsically infinite nature since it can be inferred ...

Pedro de Lucuce y Ponce y las instituciones matemático-militares españolas del siglo XVIII
(Real Sociedad Matemática Española, 2013)
Dos años después, vuelve a la sección de Historia de La Gaceta de la RSME el tema matemático-militar durante el siglo XVIII español, tema y periodo dominados por la figura del marino Jorge Juan y Santacilia (1713-1773), ...

Obtaining combinatorial structures associated with low-dimensional Leibniz algebras
(2013)
In this paper, we analyze the relation between Leibniz algebras and combinatorial structures. More concretely, we study the properties to be satisfied by (pseudo)digraphs so that they are associated with low-dimensional ...
