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, which act on spaces of analytic functions by composing with a fixed analytic self-map, are a central topic in modern functional analysis. In particular, their study on Bergman ...

An acceleration technique is developed that significantly improves the accuracy of a wide class of well-known numerical procedures for approximating the spectra of linear compact operators. A given ...

Compact equipment operators have a new tool for moving trailers more efficiently on crowded jobsites. The new loader trailer mover from Ignite Attachments is a lightweight, hitch-mounted attachment ...
