Rédigée durant l'année 2005 à AngersIn 1999, M.Chas and D.Sullivan have constructed on the homology of free loop space of a manifold a BV-algebra structure. This was the begining of the String topology theory. In this thesis, we show the compatibility of the Serre spectral sequence to Gysin morphism of smooth finite codimensional embeddings between manifolds. Then, we use this technic to compute some examples of structures of string topology. We study essentially the “loop product” and the “loop coproduct” which provide the homology of free loop space of a manifold a stucture of Frobenius algebra without counit.En 1999, M.Chas et D.Sullivan ont mis en évidence sur l'homologie de l'espace des lacets libres d'une variété une structure de BV-a...
