Phase Unwinding, or Invariant Subspace Decompositions of Hardy Spaces [PDF]

open access: yesJournal of Fourier Analysis and Applications, 2017
We consider orthogonal decompositions of invariant subspaces of Hardy spaces, these relate to the Blaschke based phase unwinding decompositions (Coifman and Steinerberger in J Fourier Anal Appl 23(4):778–809, 2017; Coifman et al.

Thermal Shrinkage‐Induced Modifications in Photonic Bandgaps of Two‐Photon Polymerized Bragg Reflectors

open access: yesAdvanced Photonics Research, EarlyView.
Scanning electron microscopy and white‐light reflectance images of the pillar‐supported distributed Bragg reflector (DBR) are presented before and after thermal shrinkage. The DBR, fabricated via two‐photon polymerization, consists of alternating high‐ and low‐index layers supported by vertical pillars.

Hardy–Littlewood maximal operators and Hausdorff operators on p-adic block spaces with variable exponents

open access: yesAIMS Mathematics
In this paper, we established some sufficient conditions for the boundedness of the Hardy–Littlewood maximal operators and the Hausdorff operators on $ p $-adic Herz spaces and $ p $-adic local block spaces with variable exponents.

Experimental Test of the Three‐Setting Clauser–Horne–Shimony–Holt Inequality with Nonmaximally Orbital Angular Momentum Entangled States

open access: yesAdvanced Photonics Research, EarlyView.
Herein, the maximum violation of the three‐setting Clauser–Horne–Shimony–Holt (CHSH) inequality using nonmaximally entangled photons with orbital angular momentum is demonstrated. By mapping the optimization problem to maximizing a triangle's perimeter inscribed in an ellipse, the experiment validates the geometric approach and highlights the ...

Some open questions in analysis for Dirichlet series

open access: yes, 2016
We present some open problems and describe briefly some possible research directions in the emerging theory of Hardy spaces of Dirichlet series and their intimate counterparts, Hardy spaces on the infinite-dimensional torus.

Hardy spaces of vector-valued Dirichlet series [PDF]

open access: yes, 2016
Given a Banach space $X$ and $1 \leq p \leq \infty$, it is well known that the two Hardy spaces $H_p(\mathbb{T},X)$ ($\mathbb{T}$ the torus) and $H_p(\mathbb{D},X)$ ($\mathbb{D}$ the disk) have to be distinguished carefully.

Vision‐Assisted Avocado Harvesting with Aerial Bimanual Manipulation

open access: yesAdvanced Robotics Research, EarlyView.
This work outlines the design and implementation of a bimanual aerial robot that employs visual perception and learning to detect, reach, and harvest avocados. A new gripper and fixer arm assembly is used to harvest avocados, while visual perception enables the detection of avocados and estimation of their position and orientation for determining ...

Convolution Operators and Bochner-Riesz Means on Herz-Type Hardy Spaces in the Dunkl Setting

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2010
We study the Dunkl convolution operators on Herz-type Hardy spaces ℋα,2p and we establish a version of multiplier theorem for the maximal Bochner-Riesz operators on the Herz-type Hardy spaces ℋα,∞p.

$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.
