These computations give nice by-products on some geometrical problems related to lens spaces. We show that J-groups of lens spaces approximate localized J-groups of complex projective spaces. We also make connections of the J-cornputations with the classical cross-section problem and the .James numbers conjecture. Many difficult geometric problems remain open. The results are related to some arithmetic on representations of cyclic groups o\er fields and the Atiyah-Segal isomormhisrn. Eventually, we are interested in representations over rings, in connection with Algebraic K-theory. This turns out to lie a very non-trivial arithmetic problem related to number theory.viii, 59 leavesEnglishinfo:eu-repo/semantics/openAccessTopological K-TheoryLens spacesRepresentations of cyclic groupsJ-groupsIm(J)-theoryAlgebraic K-theoryQA612.33 .K57 1998K-theory.Geometry, Algebraic.Representations of groups.Algebraic topology.Thesis
