DISCRETE QUADRATIC ESTIMATES AND HOLOMORPHIC FUNCTIONAL CALCULI IN BANACH SPACES EDWIN FRANKS AND ALAN McINTOSH
We develop a discrete version of the weak quadratic estimates for operators of type ! of [6], and show that analogous theorems hold. The method is direct and can be generalized to the case of nding necessary and su cient conditions for an operator T to have a bounded functional calculus on a domain which touches (T ) non-tangentially at several points. For operators on L, 1 < p <1, it follows t...
متن کاملApproximate mixed additive and quadratic functional in 2-Banach spaces
In the paper we establish the general solution of the function equation f(2x+y)+f(2x-y) = f(x+y)+f(x-y)+2f(2x)-2f(x) and investigate the Hyers-Ulam-Rassias stability of this equation in 2-Banach spaces.
متن کاملConical Square Function Estimates in Umd Banach Spaces and Applications to H∞-functional Calculi
We study conical square function estimates for Banach-valued functions, and introduce a vector-valued analogue of the Coifman–Meyer–Stein tent spaces. Following recent work of Auscher–MIntosh–Russ, the tent spaces in turn are used to construct a scale of vector-valued Hardy spaces associated with a given bisectorial operator A with certain off-diagonal bounds, such that A always has a bounded H...
متن کاملHolomorphic functions on Banach spaces
This is a survey about some problems from the theory of holomorphic functions on Banach spaces which have attracted the attention of many researchers during the last thirty years.
متن کاملDecomposable quadratic forms in Banach spaces
A continuous quadratic form on a real Banach space X is called decomposable if it is the difference of two nonnegative (i.e., positively semidefinite) continuous quadratic forms. We prove that if X belongs to a certain class of superreflexive Banach spaces, including all Lp(μ) spaces with 2 ≤ p < ∞, then each continuous quadratic form on X is decomposable. On the other hand, on each infinite-di...
