These thermo-group representations provide a unified view of different approaches for finite-temperature quantum fields in terms of a symmetry group. On these grounds, a path integral formalism is constructed, using Bogoliubov transformations, for bosons, fermions and non-abelian gauge fields. The generalization of the results for quantum fields in (S1)d×RD-d topology is addressed.Submitted by Bruna Lessa (lessbruna@gmail.com) on 2012-07-03T13:31:50Z No. of bitstreams: 1 (100)1-s2.0-S000349160900102X-main.pdf: 322638 bytes, checksum: 2cf2bbbe0cdfebc9f77774a77ee2a1a5 (MD5)Made available in DSpace on 2012-07-03T13:31:50Z (GMT).
