These exercises in close reading are meant to expose recurring symbolic isotopies hinged on two primary poles: on the one hand, a diffused allegorization of the "Fascist storm" echoed by a network of metaphors that relate to the image of bufera, but also to other semantic ramifications--exemplified for instance by references to "devilish" dances (the sardana, fandango, trescone) that conjure up further symbols of the Fascist tregenda (pp.

They cover Thurston maps, LattAaAeAeAes map quasiconformal and rough geometry, cell decompositions, expansion, Thurston maps with two or three postcritical points, visual metrics, symbolic dynamics, tile graphs, isotopies, subdivisions, quotients of Thurston maps, combinatorially expanding Thurston maps, invariant curves, the combinatorial expansion factor, the geometry of the visual sphere, relational Thurston maps and Lebesgue measure, a combinatorial characterization of LattAaAeAeAes maps, and outlook and open problems.
We need to consider the form and substance of content isotopies. In "Quasi una fantasia", we have, in sequence: "raggiorna", "barlume", the succession of signifiers "sole bioccoso", "tardo raggio", "invisibile luce", "neri segni", and the signifier "bianco", which recalls the color of snow.
On the other hand, La media noche embraces some of the isotopies of war literature, both in its classical aspects and in the modern ways of representing the human condition in contemporary warfare.
Alternatively, two links are link-homotopic if they are related by a sequence of isotopies and same-component crossing changes (see [6]).
2) two aspects of dialogism that are absent in Bakhtin's typology: a) dialogic strategies in the structuration of the poetic discourse and its subjects on different levels of the poem (speech strategies and positioning of the speaking subjects), and; b) the decomposition of a "hard" understanding of the philosophical category of the subject and/or the sociological category of the individual depicted on the level of the "poetic plot" (via motifs and themes from the more traditional theoretical perspective, or--in terms of cognitive approaches to literature--via schemes, frames and scripts, isotopies and events).
A fundamental result about the isotopic link diagrams is: Two unoriented links and are equivalent if and only if a diagram of can be transformed into a diagram of by a finite sequence of ambient isotopies of the plane and local (Reidemeister) moves of the following three types [19]:
La denonciation de la << reification >> de la femme, de sa transformation en objet est une des isotopies thematiques les plus recurrentes de toute la litterature dite << feministe >> ou feminine.
Through these interweaving isotopies Wordsworth conveys the richness of his experience, whose strong impact was to stay with him for a long time.
