Title in Portuguese
Torção de Reidemeister das formas espaciais esféricas
Keywords in Portuguese
Grupo quaterniônico
Torção de Reidemeister
Abstract in Portuguese
Neste trabalho, estudamos a ação dos grupos dos quatérnios generalizados 'Q IND.4t', nas esferas, com o objetivo de calcularmos a torção de Reidemeister dos espaços quocientes, chamados de Formas Espaciais Esféricas Quaterniônicas. Calculamos a torção de Ray-Singer das esferas, dos espaços lenticulares e do cone sobre as esferas, este último fornecendo o caso particular do disco, usando a base para a homologia definida em [27]. Para as variedades fechadas, obtivemos a torção analítica por meio do Teorema de Cheeger-Müller [7, 22], e para o disco, por meio de uma fórmula provada por Brüning e Ma em [5]
Title in English
Reidemeister torsion of spherical space forms
Keywords in English
Quaternionic group
Reidemeister torsion
Abstract in English
In this work, we study the action of the generalized quaternionic groups 'Q IND.4t' on the spheres to compute the Reidemeister torsion of the quotient spaces, which are called Quaternionic Spherical Space Forms. Using the base of the homology defined by Ray and Singer in [27] we compute also the Ray-Singer torsion of the spheres, lens spaces and the cone over the spheres. This last one provides the disc as a particular case. For the closed manifolds we obtain the analytic torsion using the Cheeger-Müller Theorem [7, 22] and for the disc using a formula proved by Brüning and Ma in [5]
