Jean-Paul Sartre: la possibilité de l'histoire
2017
Jean-Palul Sartre tra filosofia dell'esistenza e materialismo storico: la Critica della ragione dialettica
Le séminaire comme laboratoire. L'expérience de la lecture heideggérienne de Schelling en 1927/1928
2013
Reflexión acerca de la relación que existe en la obra completa de Heidegger entre los escritos publicados y los textos correspondientes a la docencia. A partir del estudio de un seminario sobre Schelling del año 1927 recientemente publicado, se muestra cómo la filosofía de Heidegger se elabora inicialmente delante del público antes de cobrar la forma de tratados.
INTIMIDAD DEL TRABAJADOR Y COMUNICACIONES ELECTRÓNICAS SEGÚN EL TRIBUNAL CONSTITUCIONAL
2016
El Tribunal Constitucional ha desempeñado un importante papel en la ponderación de los intereses enfrentados en supuestos en los que la utilización de tecnologías de la información y la comunicación en la empresa somete a examen los lindes entre el respeto a los derechos fundamentales de los trabajadores y las facultades legítimas de dirección, control y organización del empleador. El objeto de este artículo es analizar la doctrina del Tribunal Constitucional en el estudio de una de las manifestaciones concretas de la implantación generalizada de las tecnologías de la información y comunicación en la empresa, la utilización masiva de medios de comunicación electrónica como medio de comunic…
Well-behaved *-Representations
2002
This chapter is devoted to the study of the so-called well-behaved *-representations of (partial) *-algebras. Actually one may define are two notions of well-behavedness and we will discuss the relation between them. These notions are introduced in order to avoid pathologies which may arise for general *-representations and to select “nice” representations, which may have a richer theory. In Section 8.1, we construct a class {π p } of *-representations, starting from an unbounded C*-seminorm p and we define nice *-representations in {π p }, called well-behaved. We also characterize their existence. In Section 8.2, we introduce the well-behaved *-representations associated with a compatible …
*-Representations of Partial *-Algebras
2002
This chapter is devoted to *-representations of partial *-algebras. We introduce in Section 7.1 the notions of closed, fully closed, self-adjoint and integrable *-representations. In Section 7.2, the intertwining spaces of two *-representations of a partial *-algebra are defined and investigated, and using them we define the induced extensions of a *-representation. Section 7.3 deals with vector representations for a *-representation of a partial *-algebra, which are the appropriate generalization to a *-representation of the notion of generalized vectors described in Chapter 5. Regular and singular vector representations are defined and characterized by the properties of the commutant, and…
Partial {$*$}-algebras of closable operators. I. The basic theory and the abelian case
1990
This paper, the first of two, is devoted to a systematic study of partial *-algebras of closable operators in a Hilbert space (partial Op*-algebras). After setting up the basic definitions, we describe canonical extensions of partial Op*-algebras by closure and introduce a new bounded commutant, called quasi-weak. We initiate a theory of abelian partial *-algebras. As an application, we analyze thoroughly the partial Op*-algebras generated by a single closed symmetric operator.
Sur une classe d’equations du type parabolique lineaires
1996
The application of the variational method for the existence theorem, developped by J. L. Lions, for the evolution equations in Hilbert spaces to a considerably large class of systems of linear partial differential equations of parabolic type is studied by defining Hilbert spaces in relation to the elliptic operator of the system, and an example insired by the system of equations for a viscous gas is examined.
Sesquilinear forms associated to sequences on Hilbert spaces
2019
The possibility of defining sesquilinear forms starting from one or two sequences of elements of a Hilbert space is investigated. One can associate operators to these forms and in particular look for conditions to apply representation theorems of sesquilinear forms, such as Kato's theorems. The associated operators correspond to classical frame operators or weakly-defined multipliers in the bounded context. In general some properties of them, such as the invertibility and the resolvent set, are related to properties of the sesquilinear forms. As an upshot of this approach new features of sequences (or pairs of sequences) which are semi-frames (or reproducing pairs) are obtained.
D'altro canto
2020
In occasione della ripubblicazione del volume "Lo sviluppo della semiotica" di R. Jakobson, curato da U. Eco, una riscostruzione storica e una revisione concettuale del rapporto tra linguistica e semiotica.
Lifecycle of Polycystic Ovary Syndrome (PCOS): From In Utero to Menopause
2013
Context: Polycystic ovary syndrome (PCOS) is diagnosed during the reproductive years when women present with 2 of 3 of the following criteria: 1) irregular menstrual cycles or anovulation, 2) hyperandrogenism, and 3) PCO morphology. However, there is evidence that PCOS can be identified from early infancy to puberty based on predisposing environmental influences. There is also increasing information about the PCOS phenotype after menopause. The goal of this review is to summarize current knowledge about the appearance of PCOS at different life stages and the influence of reproductive maturation and senescence on the PCOS phenotype. Evidence: PubMed, the bibliography from the Evidence-Based …
