Fractional differential operators and Toeplitz matrices
Abstract
In this work we generalize to few fractional differential operators the method used to reverse differential operators d2ndx2n by inverting a Toeplitz matrix. The interest of this work is to show that the method provides by the classical analytic methods of the analysis are easily founded by this means. (Titre: Op\'erateurs diff\'erentiels fractionnaires et matrices de Toeplitz) Op\'erateurs diff\'erentiels fractionnaire et matrices de Toeplitz.) Dans ce travail on g\'en\'eralise \`a certains op\'erateurs fractionnaires la m\'ethode utlis\'ee pour pour inverser les op\'erateurs diff\'erentiels d2ndx2n en inversant une matrice de Toeplitz. L'int\'er\et de ce travail est de montrer que l'on retrouve facilement par ce moyen les r\'esultats fournis par les m\'ethodes classiques d'analyse.
