Resumen de On a result of Peetre about interpolation of operator spaces
Teresa María Signes Signes, Fernando Cobos Díaz 
We establish interpolation formulæ for operator spaces that are components of a given quasi-normed operator ideal. Sometimes we assume that one of the couples involved is quasi-linearizable, some other times we assume injectivity or surjectivity in the ideal. We also show the necessity of these suppositions.
