This volume is the proceedings of the 10th International Symposium on Applied Algebra, Algebraic Algorithms and Error-Correcting Codes (AAECC 10), held in Puerto Rico, May 1993. The aim of the AAECC meetings is to attract high-level research papers and to encourage cross-fertilization among different areas which share the use of algebraic methods and techniques for applications in the sciences of computing, communications, and engineering. The AAECC symposia are mainly devoted to research in coding theory and computer algebra. The theoryof error-correcting codes deals with the transmission of information in the presence of noise. Coding is the systematic use of redundancy in theformation of the messages to be sent so as to enable the recovery of the information present originally after it has been corrupted by (not too much)noise. Computer algebra is devoted to the investigation of algorithms, computational methods, software systems and computer languages, oriented to scientific computations performed on exact and often symbolic data, by manipulating formal expressions by means of the algebraic rules they satisfy. Questions of complexity and cryptography are naturally linked with both coding theory and computer algebra and represent an important share of the area covered by AAECC.

Los debates que se presentan en este libro son el resultado de un trabajo que, desde hace varios anos, se viene desarrollando en la asignatura Principales Corrientes del Pensamiento Contemporaneo de la Carrera de Ciencias de la Comunicacion Social (Facultad de Ciencias Sociales, Universidad de Buenos Aires). Ellos recuperan algunas de las preocupaciones que aparecen, de un modo recurrente, en gran parte del pensamiento social y politico de la convulsionada epoca contemporanea. El punto de partida para la construccion y el desarrollo de dos paradigmas de interpretacion, cuya importancia fue decisiva para interpretar el siglo XX, se encuentra en los pensamientos de Karl Marx y Max Weber.
