Políticas educativas y alfabetización mediática para una educación de calidad en España en el siglo XXI : consulta a expertos

En 2005, el Centro de información y documentación educativa(CIDE) del Ministerio de Educación español, puso en marcha el programa Mediascopio, que pretendía reactivar la Educación en medios en España. Esta iniciativa ponía fin al “silencio clamoroso” de más de diez años de la administración educativa central española con respecto a un tema fundamental en el contexto de la sociedad de la información en la que nos encontramos

Manifolds with corners modeled on convenient vector spaces

The authors of the present paper realize a quite systematic study of infinite-dimensional Banach manifolds with corners in [8]. Here, we extend some features of the manifolds with corners modeled on Banach spaces to manifolds with corners modeled on convenient vector spaces, that have arisen as important, in the last years, in Global Analysis

Proof of the equivalence of the symplectic forms derived from the canonical and the covariant phase space formalisms

We prove that, for any theory defined over a space-time with boundary, the symplectic form derived in the covariant phase space is equivalent to the one derived from the canonical formalism.Comment: Accepted in PR

Topology of the Misner space and its g-boundary

The Misner space is a simplified 2-dimensional model of the 4-dimensional Taub-NUT space that reproduces some of its pathological behaviours. In this paper we provide an explicit base of the topology of the complete Misner space ℝ¹,¹/boost. Besides we prove that some parts of this space, that behave like topological boundaries, are equivalent to the g-boundaries of the Misner space.The authors are very grateful to Juan Margalef Roig and Miguel Sánchez Caja for their useful comments and support, and specially to Fernando Barbero and Robert Geroch for their patience, comments and priceless help.
