Resumen:
We study potential spaces associated with orthogonal expansions. Inspired by some ideas of Segovia and Wheeden, we characterize these potential spaces by certain Littlewood-Paley functions involving fractional derivatives. As special cases we obtain characterizations for potential spaces associated with Hermite, Laguerre, Ornstein- Uhlenbeck and ultraspherical operators.
