Complex symmetric operators have attracted significant attention in recent years owing to their intriguing spectral properties and the elegance of their underlying mathematical structures. At their ...
Let 𝔻 be the open unit disk in ℂ and let Ω be a domain in ℂn. Every holomorphic map φ : 𝔻 → Ω induces a composition operator Cφ : H(Ω) → H(𝔻), where H(Ω) and H(𝔻) are the spaces of holomorphic ...
Every composition operator Cφ on the Lipschitz space Lip0(X) attains its norm. This fact is essentially known and we give in this paper a sequential characterization of the extremal functions for the ...
