Abstract

We work with the abstract K and J interpolation method generated by a sequence lattice Γ. We investigate the deviation of an interpolated operator from a given operator ideal by establishing formulae for the ideal measure of the interpolated operator in terms of the ideal measures of restrictions of the operator. Formulae are given in terms of the norms of the shift operators on Γ.
