Singular stochastic integral operators [PDF]

open access: yesAnalysis & PDE, 2020
In this paper we introduce Calder\'on-Zygmund theory for singular stochastic integrals with operator-valued kernel. In particular, we prove $L^p$-extrapolation results under a H\"ormander condition on the kernel.

A Note on Singular Integrals [PDF]

open access: bronzeProceedings of the American Mathematical Society, 1979
In this article we discuss what happens when we consider a convolution operator whose kernel is a Calderón-Zygmund kernel multiplied by a bounded radial function. Some generalizations are obtained.

On commutators of singular integrals and bilinear singular integrals [PDF]

open access: yesTransactions of the American Mathematical Society, 1975
LP estimates for multilinear singular integrals generalizing Calderon's commutator integral are obtained. The methods introduced involve Fourier and Mellin analysis. 1. In this paper we introduce new methods to obtain estimates for commutators of singular integrals as well as other related operators. Let A(f) = A(x)f(x) and H(f) = pvff(t)dt/(x t).

Analytic singular integral operators [PDF]

open access: goldAmerican Journal of Mathematics, 1967
The following paper extends to real analytic manifolds the general theory of singular integral operators as described in [lO] and [13]. The definition of an analytic singular integral operator is made in terms of the kernel of the operator. The symbol of the operator is discussed and in the case of an elliptic operator, a regularity theorem is proved ...
