Three-Dimensional Elastodynamic Analysis Employing Partially Discontinuous Boundary Elements

open access: yesAlgorithms, 2021
Compared with continuous elements, discontinuous elements advance in processing the discontinuity of physical variables at corner points and discretized models with complex boundaries.

$L_{p;r} $ spaces: Cauchy Singular Integral, Hardy Classes and Riemann-Hilbert Problem in this Framework [PDF]

open access: yesSahand Communications in Mathematical Analysis, 2019
In the present work the space  $L_{p;r} $ which is continuously embedded into $L_{p} $  is introduced. The corresponding Hardy spaces of analytic functions are defined as well. Some properties of the functions from these spaces are studied.

BOUNDS FOR VOLUMES OF SUB-LEVEL SETS OF POLYNOMIALS AND APPLICATIONS

open access: yesTạp chí Khoa học Đại học Đà Lạt, 2022
In this paper, we present some explicit exponents in the estimates for the volumes of sub-level sets of polynomials on bounded sets and applications to the decay of oscillatory integrals and the convergence of singular integrals.

BCR algorithm and the $T(b)$ theorem [PDF]

open access: yes, 2007
We show using the Beylkin-Coifman-Rokhlin algorithm in the Haar basis that any singular integral operator can be written as the sum of a bounded operator on $L^p ...

A singular integral [PDF]

open access: yesProceedings of the American Mathematical Society, 1986
In this paper we show that if K ( x ) = Ω ( x ) / | x | n K(x) = \Omega (x)/{\left | x \right |^n} is a Calderón-Zygmund kernel, where Ω

Algebras of Singular Integral Operators with Kernels Controlled by Multiple Norms [PDF]

open access: yesMemoirs of the American Mathematical Society, 2015
The purpose of this paper is to study algebras of singular integral operators on $\mathbb{R}^{n}$ and nilpotent Lie groups that arise when one considers the composition of Calder\'on-Zygmund operators with different homogeneities, such as operators that ...

Some one-sided estimates for oscillatory singular integrals [PDF]

open access: yes, 2014
The purpose of this paper is to establish some one-sided estimates for oscillatory singular integrals. The boundedness of certain oscillatory singular integral on weighted Hardy spaces $H^{1}_{+}(w)$ is proved. It is here also show that the $H^{1}_{+}(w)$
