In this memory of master we interest on the study of the lipchitz structure of Frechet spaces and quasi-Banach spaces, such as we concentrated on Lp and lp spaces in the case 0 < p < 1:frF-spaces, quasi-Banach spaces, the lipchitz structure.Stucture non linéaire de certains espaces (espaces de fréchet et quasi-brnach)Thesis
