Levine's motivic comparison theorem revisited

For a field of characteristic zero, M. Levine has proved that his category of triangulated motives is equivalent to the one constructed by V. Voevodsky. In this paper we show that the strategy of Levine's proof can be applied on every perfect field to the categories of triangulated motives with rational coefficients.Comment: 40 pages, submitte

Perverse Nori motives

25 pagesInternational audienceIn this work we show that the Tannakian formalism developed by M. Nori applies to representations of quivers with values in an Abelian category that is Noetherian, Artinian and has with finite dimensional Hom groups. As an application, we define a relative version, modeled after perverse sheaves, of the Abelian category of motives constructed by M. Nori over a field of characteristic embedded in the field of complex numbers

Projection constants of almost-Milyutin spaces

We prove that there exist almost-Milyutin spaces whose projection constants are numbers of the form $1+2\sum_{i=1}^{r}\left(1-\frac{1}{n_{i}}\right)$, where $n_{1},...,n_{r}$ are integers greater than 1. This generalizes our earlier results, where we showed the existence of almost-Milyutin spaces with exact projection constant greater or egual to n, for each positive integer n

Las anáforas de Cotidiano del Missale hispano-mozarabicum

Las plegarias eucarísticas o anáforas del tiempo De Gotidiano del actual Missale Hispano-Mozarabicum constituyen una fuente de especial significación para el conocimiento de la teología eucarística del rito hispanomozárabe. Lo que aquí se pretende es una breve introducción y presentación de las características fundamentales de las anáforas cotidianas del misal hispano. Con esto, el lector puede adentrarse en los textos anafóricos del tiempo De Gotidiano o de otros tiempos del misal de 1991
