The <i>g<sub>E</sub></i>-Approximation Property Determined by the Banach Space <i>E</i> = <i>ℓ<sub>q</sub></i>(<i>ℓ<sub>p</sub></i>)
Abstract
We study the gE-approximation property for the Banach space E=ℓq(ℓp), which is an extension of Saphar’s p-approximation property. We establish some characterizations of the gE-approximation property using the space of E-summing operators, which is an extension of the space of p-summing operators.
