The first (Chapter 1 to 5) is dedicated to the development and study of a procedure for the accurate computation of frequencies, as well ans the related Fourier coefficients, of a quasi-periodical function. The second part of the work (Chapters 6 to 7) is devoted to the study to the dynamics in the vicinity of the collinear equilibrium points of the three-dimensional RTBP fo the Earth-Moon mass parameter. The third part consists in several appendices, which give some additional results that have been taken apart from the main text in order to improve its readability.application/pdfeng(c) Mondelo González, 2001Anàlisi de FourierProblema dels tres cossosFuncionsÒrbitesFourier analysisThree-body problemFunctionsOrbitsinfo:eu-repo/semantics/doctoralThesisB.5515-2002info:eu-repo/semantics/openAccesshttp://www.tdx.cat/TDX-0117102-130456http://hdl.handle.net/10803/2106
