Maximal totally geodesic submanifolds and index of symmetric spaces
(2016)
Let M be an irreducible Riemannian symmetric space. The index i(M ) of M is the minimal codimension of a totally geodesic submanifold of M. In [1] we proved that i(M ) is bounded from below by the rank rk(M) of M, that is, ...
Generalized multi-terminal decoherent transport: recursive algorithms and applications to SASER and giant magnetoresistance
(2014)
Decoherent transport in mesoscopic and nanoscopic systems can be formulated in terms of the D'Amato–Pastawski (DP) model. This generalizes the Landauer–Büttiker picture by considering a distribution of local decoherent ...
Existence of strictly positive solutions for sublinear elliptic problems in bounded domains
(2014)
Let Ω be a smooth bounded domain in RN and let m be a possibly discontinuous and
unbounded function that changes sign in Ω. Let f : [0,∞) → [0,∞) be a nondecreasing
continuous function such that k1 ξp ≤ f (ξ) ≤ k2 ξp for ...
First all-sky search for continuous gravitational waves from unknown sources in binary systems
(2014)
We present the first results of an all-sky search for continuous gravitational waves from unknown
spinning neutron stars in binary systems using LIGO and Virgo data. Using a specially developed analysis
program, the ...
Aportes a la formación del profesorado constructivista : resultados en dos países
(2016)
La investigación aborda la influencia que tiene la participación en la investigación educativa en la calidad de la enseñanza de docentes de ciencias experimentales de Argentina y España. Se han utilizado tres vías de acceso ...
Spherical functions : the spheres vs the projective spaces
(2014)
In this paper we establish a close relationship between the
spherical functions of the n-dimensional sphere Sn ≃ SO(n + 1)/SO(n)
and the spherical functions of the n-dimensional real projective space
P n(R) ≃ SO(n + ...
A certified extension of the Krivine machine for a call-by-name higher-order imperative language
(2014)
In this paper we present a compiler that translates programs from an imperative higher-order language into a sequence of instructions for an abstract machine. We consider an extension of the Krivine machine for the ...
Spherical functions associated with the three dimensional sphere
(2014)
In this paper, we determine all irreducible spherical functions of any K-type associated to the pair (G;K) = (SO(4); SO(3)). This is accomplished by associating to a vector valued function H = H(u) of a real variable ...
Curvature flows for almost-hermitian Lie groups
(2015)
We study curvature flows in the locally homogeneous case (e.g. compact quotients of Lie groups, solvmanifolds, nilmanifolds) in a unified way, by considering a generic flow under just a few natural conditions on the broad ...
Matrix Gegenbauer polynomials : the 2×2 fundamental cases
(2016)
In this paper, we exhibit explicitly a sequence of 2 × 2 matrix valued orthogonal polynomials
with respect to a weight W p,n , for any pair of real numbers p and n such that 0 < p < n. The entries of these polynomiales ...
