Meyer sets, topological eigenvalues, and Cantor fiber bundles [PDF]

open access: yes, 2013
We introduce two new characterizations of Meyer sets. A repetitive Delone set in $\R^d$ with finite local complexity is topologically conjugate to a Meyer set if and only if it has $d$ linearly independent topological eigenvalues, which is if and only if

The conjugate of a hypersurface

open access: yesCommunications, Faculty Of Science, University of Ankara Series A1Mathematics and Statistics, 1998
The present paper is devoted to the study of conjugate reflectors in the \(n\)-dimensional Euclidean space \(E^n\). The authors follow, word by word, Paragraphs 3 and 4 of a paper by the reviewer and \textit{D. Koutroufiotis} [J. Geom. 24, 131-167 (1985; Zbl 0578.53002)], for reflectors in three-dimensional Euclidean space \(E^3\).

Factorizations of finite groups by conjugate subgroups which are solvable or nilpotent [PDF]

open access: yes, 2015
We consider factorizations of a finite group $G$ into conjugate subgroups, $G=A^{x_{1}}\cdots A^{x_{k}}$ for $A\leq G$ and $x_{1},\ldots ,x_{k}\in G$, where $A$ is nilpotent or solvable.

A Three-Term Conjugate Gradient Method with Sufficient Descent Property for Unconstrained Optimization [PDF]

open access: yes, 2011
Conjugate gradient methods are widely used for solving large-scale unconstrained optimization problems, because they do not need the storage of matrices.

On conjugacy of maximal abelian subalgebras and the outer automorphism group of the Cuntz algebra [PDF]

open access: yes, 2015
We investigate the structure of the outer automorphism group of the Cuntz algebra and the closely related problem of conjugacy of maximal abelian subalgebras in On.

Dermatan Sulfate: Structure, Biosynthesis, and Biological Roles

open access: yesBiomolecules
Dermatan sulfate (DS) is a remarkably versatile glycosaminoglycan that plays critical roles across a wide array of biological processes. Its unique structure, characterized by repeating disaccharide units of N-acetyl-D-galactosamine (GalNAc) and Iduronic

Conjugate but non inner conjugate subfactors [PDF]

open access: yesProceedings of the American Mathematical Society, 1996
It is shown that for each r ∈ { 4 cos 2 ⁡ ( π / n ) : n ≥ 3 } ∪ [ 4 , ∞ ) , r \in \{4\cos ^{2}(\pi /n): n \ge 3\} \cup [4, \infty ),

Pump-probe detuning dependence of four-wave mixing pulse in an SOA [PDF]

open access: yes, 2007
Four-wave mixing (FWM) between 2-ps pulses in a multiquantum-well semiconductor optical amplifier (SOA) is presented. The conjugate pulses are fully characterized using the frequency-resolved optical gating technique.

Conjugate Jacobi Series and Conjugate Functions

open access: yesJournal of Approximation Theory, 1996
The starting point is the notion of conjugacy on a Euclidean \(n\)-space as defined by \textit{E. M. Stein} and \textit{G. Weiss} [Acta Math. 103, 25-62 (1962; Zbl 0097.28501)]. Conjugate Jacobi series is introduced in the sense that the Jacobi harmonic function and the conjugate harmonic function (indicated in the title) satisfy the generalized Cauchy-
