Una Conjetura de Polya y Szego para el Tono Fundamental de Membranas Poligonales
(2010)
Polya y Szego conjeturaron que el n-polgono regular es capaz de producir el tono mas grave de entre los polgonos con n lados. La conjetura sigue abierta para todos los valores de n 5, despues de casi setenta a~nos de haber ...
Mathematical thinking, conceptual frameworks: a review of structures for analyzing problema- solving protocols
(2010)
Recently, it has been considered important to reflect on the coincidences between the mathematical thinking of the School of Mathematics and the Discipline of Mathematics. It is widely accepted that a professional mathematician ...
Extended T-Duality In Three Dimensions
(2010)
The concept of Wick duality of General Relativity in 2 + 1 dimensions with a cosmological constant is extended to the low energy effective action of bosonic string theory in 2 + 1 dimensions. We call this extension stringly ...
Three-dimensional structures of RNA obtained by means of knowledge-based interaction potentials.
(2010)
We derive a set of effective potentials describing the interaction between pairs of nucleotides that belong to an RNA molecule. Such interaction potentials are then used as the main constituents of a simplified simulation ...
Bloch Floquet waves and localisation within a heterogeneous waveguide with long cracks
(2010)
A bi-material waveguide is assumed to have an array of sufficiently long cracks parallel to the boundaries. The BlochÂFloquet waves propagating along such a waveguide are dispersive, and the band gaps are clearly identified. ...

Uso de las tecnologías en el aprendizaje de la matemática. Constructivismo y uso de las tecnologías digitales
(2010)
In this course we analyzed some characteristics of constructivist approaches to learning of mathematics. Also we discuss character of digital technologies as mediation tools.
Sistemas de Representación y el Desarrollo de Conceptos Matemáticos
(2010-08)
In this presentation I discuss the role of
semiotic representations in the construction of
mathematical knowledge
Uso de las tecnologías en el aprendizaje de la matemática. Aprendizaje y desarrollo cognitivo
(2010-01)
IN this course we analized some relationships between learning and cognitive development, based on the construct of mediates action.
