Dinmicas de Bulto y de Frontera: Perspectiva hamiltoniana (Spanish Edition),Used
Delivery time: 8-12 business days (International)
En el presente trabajo se estudian dos aspectos de la dinmica de teoras definidas en espaciotiempos con frontera. El primero es la adicin y tratamiento de los trminos de frontera temporales, los cuales son usualmente agregados a los principios de accin hamiltonianos y lagrangianos. Estos trminos de frontera son sistemticamente tratados dentro del formalismo cannico de Dirac. Una vez que el formalismo general es desarrollado, el procedimento es ilustrado en diversos ejemplos. El segundo tema es la construccin de teoras de campo de frontera a partir de cierta teoras de campo definidas sobre una 3variedad con frontera. Como primer modelo se toma a la teora de ChernSimons la cual induce una teora de campo en la frontera de la 3variedad. Como segundo modelo se toma a la teora BF. Cada modelo ser analizado aplicando un mtodo diferente y as construir un principio de accin definido en la frontera en cada caso. El conteo de grados de libertad fsicos en ambos modelos es realizado mediante el anlisis cannico de Dirac para ciertos grupo de norma particulares. Los resultados obtenidos se generalizan a dimensiones y grupos arbitrarios.
