Composition Operators between Weighted Banach Spaces of Analytic Functions
We characterize those analytic self-maps <p of the unit disc which generate bounded or compact composition operators Cv between given weighted Banach spaces H£° or H® of analytic functions with the weighted sup-norms. We characterize also those composition operators which are bounded or compact with respect to all reasonable weights v. 1991 Mathematics subject classification (Amer. Math. Soc): ...
متن کاملPointwise multiplication operators on weighted Banach spaces of analytic functions
For a wide class of weights we find the approximative point spectrum and the essential spectrum of the pointwise multiplication operator Mφ, Mφ(f)=φf , on the weighted Banach spaces of analytic functions on the disc with the sup-norm. Therefore we characterize when Mφ is Fredholm or is an isomorphism into. We study also cyclic phenomena of the adjoint map M ′ φ.
متن کاملTractability results for weighted Banach spaces of smooth functions
We study the L∞-approximation problem for weighted Banach spaces of smooth d-variate functions, where d can be arbitrarily large. We consider the worst case error for algorithms that use finitely many pieces of information from different classes. Adaptive algorithms are also allowed. For a scale of Banach spaces we prove necessary and sufficient conditions for tractability in the case of produc...
متن کاملWeighted Composition Operators and Dynamical Systems on Weighted Spaces of Holomorphic Functions on Banach Spaces
Let BX and BY be the open unit balls of the Banach SpacesX and Y , respectively. Let V and W be two countable families of weights on BX and BY , respectively. Let HV (BX) (or HV0 (BX)) and HW (BY ) (or HW0 (BY )) be the weighted Fréchet spaces of holomorphic functions. In this paper, we investigate the holomorphic mappings φ : BX → BY and ψ : BX → C which characterize continuous weighted compos...
متن کاملDifferences of weighted composition operators between weighted Banach spaces of holomorphic functions and weighted Bloch type spaces
Nosotros consideramos auto aplicaciones φ1, φ2 del disco unitario abierto bien como aplicaciones anaĺıticas ψ1, ψ2. Estas aplicaciones inducen diferencias de composición de operadores con peso actuando entre espacios de Banach pesados de funciones holomorfas y espacios de tipo Bloch con peso. En este art́ıculo damos condiciones necesarias y suficientes para que tal diferencia sea acotada, respec...
