    This textbook provides an undergraduate introduction to Galois theory and its most notable applications.Galois theory was born in the 19th century to study polynomial equations. Both powerful and elegant, this theory was at the origin of a substantial part of modern algebra and has since undergone considerable development. It remains an extremely active research subject and has found numerous applications beyond pure mathematics. In this book, the authors introduce Galois theory from a contemporary point of view. In particular, modern methods such as reduction modulo prime numbers and finite fields are introduced and put to use. Beyond the usual applications of ruler and compass constructions and solvability by radicals, the book also includes topics such as the transcendence of e and ¿, the inverse Galois problem, and infinite Galois theory.Based on courses of the authors at the École Polytechnique, the book is aimed at students with a standard undergraduate background in (mostly linear) algebra. It includes a collection of exam questions in the form of review exercises, with detailed solutions.

    Pasado, presente y futuro, estos son los tres momentos en que se mueve la conciencia día tras día y, con el tiempo, todo se vuelve cotidiano; tanto como beber café por la mañana o acariciar un poco al gato antes de salir de casa. Estamos acostumbrados al mundo, al tiempo, al espacio y a la realidad.Nos cuestionamos todo y no resolvemos nada; no entendemos nada, pero lo explicamos todo; así es como funcionamos, siempre a medias, siempre a destiempo y por eso una vida entera jamás es suficiente. Sin embargo, ¿quién soy yo para afirmar tal cosa?, nadie en realidad; tan solo un ser que ha decidido convertir en poemas la esencia de lo cotidiano y para ello ha creado este pequeño compendio que pretende hablar de la cotidianeidad humana y lo absurda que ésta puede llegar a ser. Te invito a conocer los placeres cotidianos de los que somos testigos día tras día, mismos que han sido plasmados en las páginas de este poemario. Soy un escritor silencioso; un autor sin voz, poeta de tragedias, romances, tristezas, banalidades y otras grandes emociones que convergen al interior de su poesía.
