More Examples of Hereditarily ℓp Banach Spaces

Abstract

Extending our previous result, we construct a class of hereditarily ℓp for 1 ≤ p < ∞ (c₀) Banach spaces, investigate their properties, and show that the classical Pitt theorem on compactness of operators from ℓs to ℓp for 1 ≤ p < s < ∞ is false in the general setting of hereditarily ℓs and ℓp spaces.
