The concept of a dyadic representation was used for the first time in 1963, when I constructed traces of operators (acting on a Banach space) whose sequence of approximation numbers is summable. Only recently, in a series of papers, those representations played the decisive role in describing all traces on arbitrary operator ideals over the separable infinite-dimensional Hilbert space. Now this method is extended to operator ideals on Banach spaces defined by means of generalized approximation numbers. The results are demonstrated on the example of convolution operators generated by functions belonging to certain Lipschitz/Besov spaces.
