Up-to-date coverage, including treatment of high performance fibers, superabsorbants, liquid crystal polymers, electrical conductivity, and other current topics. Emphasis on fundamental principles. Shows applications of basic principles in real materials.

Basic properties, homotopy classification, and characteristic classes of fibre bundles have become an essential part of graduate mathematical education... for students in geometry and mathematical physics. The new edition of this text includes two additional chapters, one on the gauge group of a bundle and the other on the differential forms representing characteristic classes of complex vector bundles on manifolds.

The seventeen pieces in Ficciones demonstrate the whirlwind of Borges’s genius and mirror the precision and potency of his intellect and... inventiveness, his piercing irony, his skepticism, and his obsession with fantasy. Borges sends us on a journey into a compelling, bizarre, and profoundly resonant realm; we enter the fearful sphere of Pascal’s abyss, the surreal and literal labyrinth of books, and the iconography of eternal return. To enter the worlds in Ficciones is to enter the mind of Jorge Luis Borges, wherein lies Heaven, Hell, and everything in between.

Una atípica novela social. Una apasionante trama de suspenso, con el telón de fondo de la crisis del neoliberalismo y las protestas contra la... globalización. Río Fugitivo vive la semana decisiva de una revuelta popular contra el alza de las tarifas de energía eléctrica hecha por una transnacional. A las tradicionales manifestaciones callejeras, se suma una nueva forma de protesta para un nuevo siglo: la guerra electrónica, los virus informáticos. En este enfrentamiento se entrecruzan los destinos de varios personajes: Kandinsky, hijo de un minero relocalizado, es el mítico líder de un grupo de hackers que combate al gobierno y a las transnacionales; Albert es el fundador, en tiempos de dictadura, de la Cámara Negra, organismo de seguridad del Estado encargado de descifrar las claves y códigos secretos de los opositores; Miguel Sáenz –conocido como Turing-, el más famoso descifrador de códigos de la Cámara Negra, comienza a sospechar que su trabajo durante la dictadura no fue tan inocente como él creía. Edmundo Paz Soldán ha escrito el complejo capitulo contemporáneo de la vieja lucha entre los creadores de mensajes secretos y sus descifradores, entre los opresores y los oprimidos. Edmundo Paz Soldán Biographie:Edmundo Paz Soldán (Bolivia, 1967) is one of the most influential Bolivian writers of the new generation. He holds a PhD in Hispanic Literature and Languages from the University in California, Berkeley and is currently a professor at Cornell University. He was awarded the 1997 Juan Rulfo Prize for his story "Dochera". Some of his works include Río fugitivo (Alfaguara, 1998), Amores imperfectos (Alfaguara, 1998), Sueños digitales (Alfaguara, 2000), La material del deseo (Alfaguara, 2001) and Simulacros (Santillana, 1999). He also co-edited the anthology Se habla español (Alfaguara, 2000).

Ficciones es una obra imprescindible en la literatura contemporánea que merece su lugar destacado en cualquier canon de la literatura universal. Aquí... se reúnen dos libros de Borges: El jardín de senderos que se bifurcan (1941) que incluye ocho relatos y Artificios (1944) con nueve cuentos. En esta colección, Borges nos lleva de viaje por un reino extraño, irresistible y profundamente resonante. Entramos en la temerosa esfera del abismo de Pascal, el laberinto de libros surrealista y a su vez literal y la iconografía del eterno regreso. Al adentrarse en los mundos de Ficciones podrá llegar a la mente de Jorge Luis Borges, donde encontrará el Cielo, el Infierno y el poder infinito de su inteligencia e imaginación.

Ficciones es quiza el libro mas reconocido de Jorge Luis Borges. Entre los cuentos que se reunen aqui hay algunos de corte policial, como La muerte y la... brujula, otros sobre libros imaginarios, como Tlon, Uqbar, Orbis Tertius, y muchos pertenecientes al genero fantastico, como Las ruinas circulares o El sur, acaso su mejor relato, en palabras del mismo autor. Esta compuesto por los libros El jardin de senderos que se bifurcan (1941) y Artificios (1944), considerados piezas fundamentales del universo borgeano.

En Español: Una de las colecciones literarias más importantes del siglo veinte, los dieciocho cuentos contenidos en la obra Ficciones de Jorge Luis... Borges invitan al lector a reexaminar sus previas suposiciones y preocupaciones relativas a la naturaleza del universo. Desde “Tlön, Uqbar, Orbis Tertius”, el relato que, según muchos críticos, predijo la creación de Internet, y “Examen de la obra de Herbert Quain”, que combina la prueba matemática con la reseña literaria, hasta “El Sur”, una amalgama de fantasía, autobiografía, y folklórica argentina (y que Borges una vez dijo que era su cuento preferido), estas Ficciones abarcan lo esencial del inimitable estilo borgesiano.

“Pensé en un laberinto de laberintos, en un sinuoso laberinto creciente que abarcara el pasado y el porvenir y que implicara de algún modo los... astros”. —Jorge Luis Borges Ficciones es quizá el libro más reconocido de Jorge Luis Borges, compuesto por los libros El jardín de senderos que se bifurcan y Artificios, ambos considerados piezas fundamentales del universo borgiano. Entre los cuentos que aquí se reúnen hay algunos de corte policial como “La muerte y la brújula”, la historia de un  detective que investiga el asesinato de un rabino; otros sobre libros imaginarios como “Tlön, Uqbar, Orbis Tertius”, una extraordinaria reflexión sobre la literatura y su influencia en el mundo físico;  y muchos pertenecientes al género fantástico como “El Sur”, acaso su mejor relato, en palabras del mismo autor. Fascinante y sorprendente, Ficciones le brinda al lector un mundo de reflexiones sobre las convenciones de lectura y el modo de entender la realidad.
