The theory of the strong interaction is quantum chromodynamics, which is treated in perturbation theory.  after a short introduction to the relevant effective theories, which are derived from qcd, some new results are presented. First the asymptotic behaviour of the perturbative series is investigated, and the second result are proofs of factorization theorems which are used to separate the perturbative from the non-perturbative contributions.  finally, the symmtries of the effective field theories are used to find relations  between the non-perturbative matrix elements involved in  \u00abheavy to light currents\u00bb.<\/p>\n<p>&nbsp;<\/p>\n<h3>Datos acad\u00e9micos de la tesis doctoral \u00ab<strong>Qcd aspects of heavy to light currents<\/strong>\u00ab<\/h3>\n<ul>\n<li><strong>T\u00edtulo de la
