As a consequence, we deduce that certain Uryson integral operators are compact. We also show that Lipschitz operators can be interpolated by a wide class of J-functors.engjournal articlehttp://blms.oxfordjournals.org/content/22/3/273.full.pdf+htmlhttp://www.cambridge.org/restricted access517.98Análisis funcional y teoría de operadores
