On the restriction of the Fourier transform to polynomial curves [PDF]

open access: yes, 2007
We prove a Fourier restriction theorem on curves parametrised by the mapping P(t) = (P1(t),..., Pn(t)), where each of the P1,..., Pn is a real-valued polynomial and t belongs to an interval on which each of the P1,..., Pn "resembles" a ...

Homogeneous Fourier Multipliers in the Plane [PDF]

open access: yesProceedings of the American Mathematical Society, 1991
Given a homogeneous of degree zero function on the plane, we study conditions on the first derivative of its restriction to the unit circle in order to deduce that it is an L

On Radial and Conical Fourier Multipliers [PDF]

open access: yesJournal of Geometric Analysis, 2010
We investigate connections between radial Fourier multipliers on $R^d$ and certain conical Fourier multipliers on $R^{d+1}$. As an application we obtain a new weak type endpoint bound for the Bochner-Riesz multipliers associated to the light cone in $R^{d+1}$, where $d\ge 4$, and results on characterizations of $L^p\to L^{p,ν}$ inequalities for ...

Optimisation of multiplier-less FIR filter design techniques [PDF]

open access: yes
This thesis is concerned with the design of multiplier-less (ML) finite impulse response (FIR) digital filters. The use of multiplier-less digital filters results in simplified filtering structures, better throughput rates and higher speed.

Uncertainty Principles for Fourier Multipliers [PDF]

open access: yesJournal of Fourier Analysis and Applications, 2020
The admittable Sobolev regularity is quantified for a function, $w$, which has a zero in the $d$--dimensional torus and whose reciprocal $u=1/w$ is a $(p,q)$--multiplier. Several aspects of this problem are addressed, including zero--sets of positive Hausdorff dimension, matrix valued Fourier multipliers, and non--symmetric versions of Sobolev ...

Linear Peridynamics Fourier Multipliers and Eigenvalues

open access: yesJournal of Peridynamics and Nonlocal Modeling, 2023
A characterization for the Fourier multipliers and eigenvalues of linear peridynamic operators is provided. The analysis is presented for state-based peridynamic operators for isotropic homogeneous media in any spatial dimension. We provide explicit formulas for the eigenvalues in terms of the space dimension, the nonlocal parameters, and the material ...

Stable sampling and Fourier multipliers [PDF]

open access: yesPublicacions Matemàtiques, 2014
We study the relationship between stable sampling sequences for bandlimited functions in $L^p(\R^n)$ and the Fourier multipliers in $L^p$. In the case that the sequence is a lattice and the spectrum is a fundamental domain for the lattice the connection is complete. In the case of irregular sequences there is still a partial relationship.
