We present a discussion of some properties for the injective hull of this ideal and relate this work to the classes of unconditionally p-compact and quasi unconditionally p-nuclear operators.enLinear operator ideals, compact operator, Unconditionally p-summable sequences, Classical p-compact operator.Thesis
