Del castillo al burgo. El itinerario viajero en los comienzos de la narrativa medieval

The concept of man as homo viator portraits the manifestations of civilization of the medieval Christian Western. In the beginnings of its literature the travel is particularly important for the development of the narrative. Chivalric literature of the twelfth century (Chrétien de Troyes) places the travel itinerary of his characters in a particular space to be distinguished from the narrations of a few years later (Jean Renart) which are situated in a new space. The transition from the castle to the town is more than a change of set, it shows a new perception of the reality that prepares the following narrative and the emergence of travel books in the second half of the century.La concepción del ser humano como homo viator caracteriza las manifestaciones de civilización del occidente medieval cristiano. Los comienzos de su literatura dan al viaje una especial importancia para el desarrollo de la narración. La literatura caballeresca del siglo XII (Chrétien de Troyes) coloca el itinerario viajero de sus personajes en un espacio peculiar que se va diferenciar de las narraciones de unos años después (Jean Renart) que se sitúan en un nuevo espacio. El paso del castillo al burgo supone, más que un cambio de decorado, una nueva percepción de la realidad que prepara la narrativa posterior y la aparición de los libros de viaje en la segunda mitad del mismo siglo

La añoranza del placer de la comida en el Roman du Comte d’Anjou

Este trabajo analiza aquellos fragmentos del Roman du comte d’Anjou de Jean Maillart (1316) en los que sus personajes experimentan la añoranza de los placeres de la buena mesa, y los relaciona con otros fragmentos de obras anteriores, como La Belle Hélène de Constantinople (anónima) y La Manekine de Philippe de Remy.This work analyses parts of the Roman du comte d’Anjou by Jean Maillart (1316) in which the characters miss the pleasure for eating good, and establishes parallelisms with other literary works, such as La Belle Hélène de Constantinople (anonymous) and La Manekine by Philippe de Remy

El más allá al final del camino. De Chrétien de Troyes y Montalvo a Conrad y Céline

Knight’s travel, following the Chrétien de Troyes model, culminates and comes to an end with the adventure in an extraordinary space and facing supernatural creatures. This kind of adventure, that typifies the two most representative Chrétien’s romans (Erec et Enid and Yvain), will be reproduced with accuracy at the end of the First Book of the Amadís. The African journeys of the J. Conrad’s (Heart of Darkness, 1902) and Céline’s characters (Voyage au bout de la nuit, 1932) reproduce the model of the voyage to the underworld of the mentioned medieval texts, with the same features

Integral characterization for Poincaré half-maps in planar linear systems

The intrinsic nature of a problem usually suggests a first suitable method to deal with it. Unfortunately, the apparent ease of application of these initial approaches may make their possible flaws seem to be inherent to the problem and often no alternative ways to solve it are searched for. For instance, since linear systems of differential equations are easy to integrate, Poincaré half-maps for piecewise linear systems are always studied by using the direct integration of the system in each zone of linearity. However, this approach is accompanied by two important defects: due to the different spectra of the involved matrices, many cases and strategies must be considered and, since the flight time appears as a new variable, nonlinear complicated equations arise. This manuscript is devoted to present a novel theory to characterize Poincaré half-maps in planar linear systems, that avoids the computation of their solutions and the problems it causes. This new perspective rests on the use of line integrals of a specific conservative vector field which is orthogonal to the flow of the linear system. Besides the obvious mathematical interest, this approach is attractive because it allows to simplify the study of piecewise-linear systems and deal with open problems in this field.Ministerio de Economía y Competitividad (Spain) / FEDER MTM2014-56272-C2-1-PMinisterio de Economía y Competitividad (Spain) / FEDER MTM2015-65608-PMinisterio de Economía y Competitividad (Spain) / FEDER MTM2017-87915-C2-1-PMinisterio de Economía y Competitividad (Spain) / FEDER PGC2018-096265-B-I00Consejería de Educación y Ciencia de la Junta de Andalucía (Spain) TIC-0130Consejería de Educación y Ciencia de la Junta de Andalucía (Spain) P12-FQM-1658Consejería de Educación y Ciencia de la Junta de Andalucía (Spain) P20_0116
