Resumen
- The Besov characteristic of a distribution f is the function sf defined for 0 = t < 8 by We give in this paper a criterion for a function G defined on [0, +8[ to be the Besov characteristic of a distribution. Generalizations of this criterion to particular weighted Besov spaces and to anisotropic Besov spaces are also given.
