Tipos de homotopia dos grupos de gauge dos fibrados linhas quaterniônicos sobre esferas / Homotopy type of Gauge groups of quaternionic line bundles over spheres

Claudio, Mario Henrique Andrade 12 June 2008 (has links)
Seja p um \'S POT. 3\' - fibrado principal sobre uma esfera \'S POT. n\' , com n \' >OU=\' 4 . O objetivo deste trabalho é calcular os tipos de homotopia do grupo de gauge \'G IND. p\' desses fibrados p, estendendo o resultado determinado por A. Kono [25] quando n = 4. Apresentamos fórmulas explícitas para o operador bordo na seqüência exata de homotopia associada com a aplicação avaliação ev : m(\'S POT. n\' , B \'S POT. 3\' ) \'SETA\' B \'S POT. 3\' , traduzindo o problema nos cálculos envolvendo grupos de homotopia de esferas. Calculamos todos os casos clássicos, ou seja, aqueles que podem ser avaliados usando as informações encontradas no livro de H. Toda [46], determinando o tipo de homotopia do grupo de gauge desses fibrados para cada n \' > OU =\' 25 / Let p be a principal \'S POT. 3\' - bundle over a sphere \'S POT. n\' , with n\' > or =\' 4\'. The subject of this work is to calculate the homotopy type of the gauge group \'G IND. p\' of these bundles p, extending the result determined by A. Kono [25] when n = 4. We present explicit formulas for the boundary operator in the homotopy exact sequence associated with the evaluation map ev : m(\'S POT. n\' , B \'S POT. 3\' ) \' ARROW\' B \'S POT. 3\' , translating that problem into calculations involving homotopy groups of sphere. We calculate all the classical cases, namely those that can be dealt with using the information in the book of H. Toda [46], determining the homotopy type of the gauge group of these bundles for each n \'> or = 25
