Fourier analysis on the Heisenberg group [PDF]

Proceedings of the National Academy of Sciences, 1977
We obtain a usable characterization of the (group) Fourier transform of 𝒮(H n ) (Schwartz space on the Heisenberg group). The characterization involves writing elements of [Formula: see text] as asymptotic series in Planck's constant.

Dorronsoro's theorem in Heisenberg groups [PDF]

Bulletin of the London Mathematical Society, 2020
A theorem of Dorronsoro from the 1980s quantifies the fact that real-valued Sobolev functions on Euclidean spaces can be approximated by affine functions almost everywhere, and at all sufficiently small scales. We prove a variant of Dorronsoro's theorem in Heisenberg groups: functions in horizontal Sobolev spaces can be approximated by affine functions

Gradient flow of Einstein-Maxwell theory and Reissner-Nordström black holes

Journal of High Energy Physics, 2023
Ricci flow is a natural gradient flow of the Einstein-Hilbert action. Here we consider the analog for the Einstein-Maxwell action, which gives Ricci flow with a stress tensor contribution coupled to a Yang-Mills flow for the Maxwell field.

NET-(works) in arterial and venous thrombo-occlusive diseases

Frontiers in Cardiovascular Medicine, 2023
Formation of Neutrophil Extracellular Traps (NETosis), accompanied by the release of extracellular decondensed chromatin and pro-inflammatory as well as pro-thrombotic factors, is a pivotal element in the development and progression of thrombo-occlusive ...

Surjektifitas Pemetaan Eksponensial untuk Grup Lie Heisenberg yang Diperumum

Jambura Journal of Mathematics, 2023
The Heisenberg Lie Group is the most frequently used model for studying the representation theory of Lie groups. This Lie group is modular-noncompact and its Lie algebra is nilpotent.

Hölder Regularity of Quasiminimizers to Generalized Orlicz Functional on the Heisenberg Group

Journal of Function Spaces, 2020
In this paper, we apply De Giorgi-Moser iteration to establish the Hölder regularity of quasiminimizers to generalized Orlicz functional on the Heisenberg group by using the Riesz potential, maximal function, Calderón-Zygmund decomposition, and covering ...

Uncertainty Principles for Heisenberg Motion Group

Abstract and Applied Analysis, 2021
In this article, we will recall the main properties of the Fourier transform on the Heisenberg motion group G=ℍn⋊K, where K=Un and ℍn=ℂn×ℝ denote the Heisenberg group.
