Multilinear singular integrals [PDF]
Publicacions Matemàtiques, 2002 We survey the thoery of multilinear singular integral operators with modulation symmetry. The basic example for this theory is the bilinear Hilbert transform and its multilinear variants.

Investigation on the Singularities of Some Singular Integrals
Computer Modeling in Engineering & Sciences, 2019 In a boundary element method, the treatment of all the possible singular integrals is very important for the correctness and accuracy of the solutions. Generally, the directional derivative of a weakly singular integral is computed by an integral in the ...

On commutators of singular integrals and bilinear singular integrals [PDF]
Transactions 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).

Design of quadrature rules for Müntz and Müntz-logarithmic polynomials using monomial transformation [PDF]
, 2009 A method for constructing the exact quadratures for Müntz and Müntz-logarithmic polynomials is presented. The algorithm does permit to anticipate the precision (machine precision) of the numerical integration of Müntz-logarithmic polynomials in terms of ...

Boundedness of p-Adic Singular Integrals and Multilinear Commutator on Morrey-Herz Spaces
Journal of Function Spaces, 2023 In this paper, we establish the boundedness of classical p-adic singular integrals on Morrey-Herz spaces, as well as the boundedness of multilinear commutator generated by p-adic singular integral operators and Lipschitz functions or by p-adic singular ...
