Conical square function estimates in UMD Banach spaces and applications to H-infinity functional calculi

, 2007
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-McIntosh-Russ, the tent spaces in turn are used to construct a scale ...

L^p(L^q)-Maximal Regularity for Damped Equations in a Cylindrical Domain

Fractal and Fractional
We show maximal regularity estimates for the damped hyperbolic and strongly damped wave equations with periodic initial conditions in a cylindrical domain.

Two weight inequality for vector-valued positive dyadic operators by parallel stopping cubes [PDF]

, 2015
We study the vector-valued positive dyadic operator \[T_\lambda(f\sigma):=\sum_{Q\in\mathcal{D}} \lambda_Q \int_Q f \mathrm{d}\sigma 1_Q,\] where the coefficients $\{\lambda_Q:C\to D\}_{Q\in\mathcal{D}}$ are positive operators from a Banach lattice $C$

Representations of Solutions of Time-Fractional Multi-Order Systems of Differential-Operator Equations

Fractal and Fractional
This paper is devoted to the general theory of systems of linear time-fractional differential-operator equations. The representation formulas for solutions of systems of ordinary differential equations with single (commensurate) fractional order is known

The local non-homogeneous Tb theorem for vector-valued functions [PDF]

, 2012
We extend the local non-homogeneous Tb theorem of Nazarov, Treil and Volberg to the setting of singular integrals with operator-valued kernel that act on vector-valued functions.

Gleason-Type Derivations of the Quantum Probability Rule for Generalized Measurements

, 2003
We prove a Gleason-type theorem for the quantum probability rule using frame functions defined on positive-operator-valued measures (POVMs), as opposed to the restricted class of orthogonal projection-valued measures used in the original theorem.

Fourier multiplier theorems involving type and cotype [PDF]

, 2017
In this paper we develop the theory of Fourier multiplier operators $T_{m}:L^{p}(\mathbb{R}^{d};X)\to L^{q}(\mathbb{R}^{d};Y)$, for Banach spaces $X$ and $Y$, $1\leq p\leq q\leq \infty$ and $m:\mathbb{R}^d\to \mathcal{L}(X,Y)$ an operator-valued symbol ...

Composition operators on vector-valued BMOA and related function spaces [PDF]

, 2006
A composition operator is a linear operator between spaces of analytic or harmonic functions on the unit disk, which precomposes a function with a fixed self-map of the disk.

The UMD constants of the summation operators

, 2004
The UMD property of a Banach space is one of the most useful properties when one thinks about possible applications. This is in particular due to the boundedness of the vector-valued Hilbert transform for functions with values in such a space.
