Oscillatory Singular Integrals with Rough Kernel

1995
This paper is devoted to the study on the L p -boundedness for the oscillatory singular integral defined by $$ Tf(x) = p.v.\int_{\mathbb{R}^n } {e^{iP(x,y)} } K(x - y)f(y)dy, $$ where P(x,y) is a real polynomial on ℝ n × ℝ n , and \( K(x) = \frac{{h(\mid x\mid \Omega (x)}} {{\mid x\mid ^n }} \) with Ω ∈ Llog + L(S n−1) and h ∈ BV(ℝ+) (i.e.

Chapter Four. Hölder Regularity for Generalized Master Equations with Rough Kernels

, 2014
We prove Hölder estimates for integro-differential equations related to some continuous time random walks. These equations are nonlocal both in space and time and recover classical parabolic equations in limit cases.

A note concerning Marcinkiewicz integral with rough kernel

Infinite Dimensional Analysis, Quantum Probability and Related Topics, 2021
In this paper, applying some properties of rough kernel and using some technical lemmas, we prove various norm inequalities concerning Marcinkiewicz integral with rough kernel. Indeed, we extend some known results on singular integrals to Marcinkiewicz integrals.

Rough bilinear fractional integrals with variable kernels

Frontiers of Mathematics in China, 2010
We study the rough bilinear fractional integral $$ \tilde B_{\Omega ,\alpha } (f,g)(x) = \int_{\mathbb{R}^n } {f(x + y)g(x - y)\frac{{\Omega (x,y')}} {{\left| y \right|^{n - \alpha } }}dy} , $$ , where 0 < a < n, Ω is homogeneous of degree zero on the y variable and satisfies Ω ∈ L∞(ℝn)× Ls(Sn−1) for some s ⩾ 1, and Sn−1 denotes the unit sphere ...

Rough Cluster Algorithm Based on Kernel Function

2008
By means of analyzing kernel clustering algorithm and rough set theory, a novel clustering algorithm, rough kernel k-means clustering algorithm, was proposed for clustering analysis. Through using Mercer kernel functions, samples in the original space were mapped into a highdimensional feature space, which the difference among these samples in sample ...

Boundedness of Multilinear Commutators with Rough Kernels on Morrey-Herz Spaces

, 2013
This paper is concerning the commutators generated by the multilinear singular integral with rough kernels and BMO functions. The boundedness of the multilinear commutators Tb(f) is established on the Morrey-Herz space by using the JohnNirenberg ...

Rough Kernel Clustering Algorithm with Adaptive Parameters

2011
Through analyzing kernel clustering algorithm and rough set theory, a novel clustering algorithm, Rough kernel k-means clustering algorithm with adaptive parameters, is proposed for clustering analysis in this paper. By using Mercer kernel functions, we can map the data in the original space to a highdimensional feature space, in which we can use rough

On a Class of Singular Integral Operators With Rough Kernels

Canadian Mathematical Bulletin, 2006
AbstractIn this paper, we study the Lp mapping properties of a class of singular integral operators with rough kernels belonging to certain block spaces. We prove that our operators are bounded on Lp provided that their kernels satisfy a size condition much weaker than that for the classical Calderón–Zygmund singular integral operators.
