Subelliptic pseudo-differential operators and Fourier integral operators on compact Lie groups

D Cardona, M Ruzhansky - arXiv preprint arXiv:2008.09651, 2020 - arxiv.org
In this memoir we extend the theory of global pseudo-differential operators to the setting of
arbitrary sub-Riemannian structures on a compact Lie group. More precisely, given a …

Harmonic analysis on the Möbius gyrogroup

M Ferreira - Journal of Fourier Analysis and Applications, 2015 - Springer
In this paper we propose to develop harmonic analysis on the Poincaré ball B _ t^ n B tn, a
model of the n n-dimensional real hyperbolic space. The Poincaré ball B _ t^ n B tn is the …

Gabor frames from contact geometry in models of the primary visual cortex

We introduce a model of the primary visual cortex (V1), which allows the compression and
decomposition of a signal by a discrete family of orientation and position dependent …

Orthogonal wavelet frames on manifolds based on conformal mappings

S Bernstein, P Keydel - Frames and Other Bases in Abstract and Function …, 2017 - Springer
Wavelets can be interpreted as coherent states and this group theoretic approach is very
successful. Unfortunately, this approach fails on spheres and other manifolds. In this paper …

Gabor Frames and Contact Geometry: From models of the primary visual cortex to higher dimensional signal analysis on manifolds

V Liontou - 2023 - search.proquest.com
This thesis has two objectives: first, to provide a model of the functional architecture of the
primary visual cortex (V 1) in terms of both geometry and signal analysis and second to …

[PDF][PDF] Wavelets in clifford analysis
