We investigate the ideal 𝒦up, 1 ≤ 𝑝 ≤ ∞, of unconditionally 𝑝-compact operators. We obtain theisometricidentities 𝒦up = 𝒦up o 𝒦up, K up max = L p* sur , K up min = ⊗ ^ / w p* and K up = N up ...
Composition operators, defined by the rule f ↦ f ∘ φ for an analytic function φ, have long been a pivotal tool in analysing the interplay between different function spaces. In particular, Bloch-type ...
