Algebraic Calderón-Zygmund theory

نویسندگان

چکیده

Calderón-Zygmund theory has been traditionally developed on metric measure spaces satisfying additional regularity properties. In the lack of good metrics, we introduce a new approach for general which admit Markov semigroup purely algebraic assumptions. We shall construct an abstract form ‘Markov metric’ governing process and naturally associated BMO spaces, interpolate with Lp-scale endpoint inequalities operators. Motivated by noncommutative harmonic analysis, this gives first arbitrary von Neumann algebras, but is also valid in classical settings like Riemannian manifolds nonnegative Ricci curvature or doubling/nondoubling spaces. Other less standard commutative scenarios fractals probability are included. Among our applications setting, improve recent results quantum Euclidean group respectively linked to geometry geometric theory.

Weighted norm inequalities for Toeplitz type operators associated to generalized Calderón–Zygmund operators

Let [Formula: see text] be a generalized Calderón-Zygmund operator or [Formula: see text] ( the identity operator), let [Formula: see text] and [Formula: see text] be the linear operators, and let [Formula: see text]. Denote the Toeplitz type operator by [Formula: see text]where [Formula: see text] and [Formula: see text] is fractional integral operator. In this paper, we establish the sharp ma...

Fe b 20 00 BMO , H 1 , AND CALDERÓN - ZYGMUND OPERATORS FOR NON DOUBLING MEASURES

Given a Radon measure μ on R, which may be non doubling, we introduce a space of type BMO with respect to this measure. It is shown that many properties which hold for the classical space BMO(μ) when μ is a doubling measure remain valid for the space of type BMO introduced in this paper, without assuming μ doubling. For instance, Calderón-Zygmund operators which are bounded on L(μ) are also bou...

An Algebra Containing the Two-Sided Convolution Operators

We present an intrinsically defined algebra of operators containing the right and left invariant Calderón-Zygmund operators on a stratified group. The operators in our algebra are pseudolocal and bounded on Lp (1 < p <∞). This algebra provides an example of an algebra of singular integrals that falls outside of the classical Calderón-Zygmund theory.
