A note on the star order in Hilbert spaces [PDF]
, 2010 We study the star order on the algebra L(H) of bounded operators on a Hilbert space H. We present a new interpretation of this order which allows to generalize to this setting many known results for matrices: functional calculus, semi-lattice properties,

Metric geodesics of isometries in a Hilbert space and the extension problem [PDF]
, 2007 We consider the problem of finding short smooth curves of isometries in a Hilbert space H. The length of a smooth curve γ(t), t ∈ [0, 1], is measured by means of ∫^1-0 γ^. (t)ǀǀ dt, where ǀǀ ǀǀ denotes the usual norm of operators.

En los entresijos de una lista de comedias de Calderón
Revista de Filología Española, 2009 Don Juan de Vera Tassis publicó en 1682 dos listas de comedias que circulaban con el nombre de Calderón. En una de ellas enumeraba las que consideraba realmente suyas, y en la otra las que creía que no lo eran.

Robust dual reconstruction systems and fusion frames [PDF]
, 2011 We study the duality of reconstruction systems, which are g-frames in a finite dimensional setting. These systems allow redundant linear encoding-decoding schemes implemented by the so-called dual reconstruction systems. We are particularly interested in

Differential structure of the Thompson components of selfadjoint operators [PDF]
, 2008 Different equivalence relations are defined in the set L(H)s of self- adjoint operators of a Hilbert space H in order to extend a very well known relation in the cone of positive operators.

Juan de Vera Tassis, editor de Calderón: el caso de Amar después de la muerte
Revista de Filología Española, 2006 Las ediciones de las comedias de Calderón que, en la década después de su muerte, hiciera Juan de Vera Tassis y Villarroel, han servido durante siglos de base para nuevas ediciones.

The Calderón problem for the fractional Schrödinger equation with drift [PDF]
Calculus of Variations and Partial Differential Equations, 2018 We investigate the Calderón problem for the fractional Schrödinger equation with drift, proving that the unknown drift and potential in a bounded domain can be determined simultaneously and uniquely by an infinite number of exterior measurements.
