Ergodic solenoids and generalized currents

We introduce the concept of solenoid as an abstract laminated space. We do a thorough study of solenoids, leading to the notion of ergodic and uniquely ergodic solenoids. We define generalized currents associated with immersions of oriented solenoids with a transversal measure into smooth manifolds, generalizing Ruelle-Sullivan currents.Comment: 28 pages, 2 figures.

Ergodic solenoidal homology: density of ergodic solenoids

A measured solenoid is a laminated space endowed with a tranversal measure invariant by holonomy, as defined in arXiv:0910.2836. A measured solenoid immersed in a smooth manifold produces a closed current (known as generalized Ruelle-Sullivan current). Uniquely ergodic solenoids are those for which there is a unique (up to scalars) transversal measure. By the results in arXiv:0910.2913, for any smooth manifold, any real homology class is represented by a uniquely ergodic solenoid. In this paper, we prove that the currents associated to uniquely ergodic solenoids are dense in the space of closed currents, therefore proving the abundance of such objects.Comment: 9 pages, 2 figure

Estrategias retóricas para la escritura autobiográfica en la historia de las Indias de Fray Bartolomé de las casas

Lo autobiográfico en la Historia de las Indias no debe ser comprendido como una muestra más de la incontrolable subjetividad del obispo de Chiapa porque la autoescritura estuvo regulada por la historiografía. En una historia diferente el dominico asumió un papel protagónico-ejemplar. La propia presentación siguió el modelo de la confesión y proyectó dos facetas de la actuación del obispo: el justo y la del elegido. Para acreditar su biografismo usó varios recursos como señalar sus atributos morales y crear un efecto de distancia entre narrador y personaje

Ricardo Palma ethos in its tradiciones

The role of the ethos of the writer in the likelihood of a literary form called ‘tradition’, where you play with data from written sources and oral tradition, invented in the nineteenth century by the Peruvian Ricardo Palma to generate social consensus is analyzed about the identity of his nascent country.Se analiza el papel que juega el ethos del escritor en la verosimilitud de una forma literaria denominada ‘tradición’ —donde se juega con datos de fuentes escritas y de tradición oral—, inventada en el siglo XIX por el peruano Ricardo Palma para generar consensos sociales en torno a la identidad de su naciente patria

El Extremo Oriente y la condición del indio en el siglo XVI

This article seeks to verify that during the process of historical concretion of the New World and its inhabitants during the XVI century, differentiation from the nations and inhabitants of East Asia played an important role. Although the idea of the Asian condition of America, the Fourth Part of the World, was soon abandoned, the newly discovered world continued to be interpreted from the perspective of some elements that characterized the East Indies. In this sense, that region continued to be a cultural, geographical and historical reference pattern for the America
