Orthogonal color bases for exotic representations [PDF]

open access: yesPhysics Letters B
A complication in the treatment of any strongly charged particle is the SU(3) color structure. For the standard model quarks, antiquarks and gluons there are various well-known strategies for dealing with the color structure, including orthogonal ...

Squeezable Orthogonal Bases: Accuracy and Smoothness [PDF]

open access: yesSIAM Journal on Numerical Analysis, 2002
In this paper, the authors present a method for generating local orthogonal bases on arbitrary partitions on \(\mathbb{R}\) from a given local orthogonal shift-invariant basis via a so-called squeeze map. Necessary and sufficient conditions for a squeeze map are given to generate a nonuniform basis that preserves any smoothness and/or accuracy (i.e ...

Shift-orthogonal wavelet bases [PDF]

open access: yesIEEE Transactions on Signal Processing, 1998
Summary: Shift-orthogonal wavelets are a new type of multiresolution wavelet bases that are orthogonal with respect to translation (or shifts) within one level but not with respect to dilations across scales. The present authors characterize these wavelets and investigate their main properties by considering two general construction methods.

Algebras with unconditional orthogonal bases [PDF]

open access: yesProceedings of the American Mathematical Society, 1980
This is a continuation of our study of topological algebras with orthogonal Schauder bases. In the previous paper, the structure of closed ideals was determined and it was shown that the closed-maximal ideal space is homeomorphic with the discrete space of positive integers.

Orthogonal Hessenberg Reduction and Orthogonal Krylov Subspace Bases [PDF]

open access: yesSIAM Journal on Numerical Analysis, 2005
We study necessary and sufficient conditions that a nonsingular matrix A can be B-orthogonally reduced to upper Hessenberg form with small bandwidth. By this we mean the existence of a decomposition AV=VH, where H is upper Hessenberg with few nonzero bands, and the columns of V are orthogonal in an inner product generated by a hermitian positive ...

Orthogonal bases of invariants in tensor models [PDF]

open access: yesJournal of High Energy Physics, 2018
Representation theory provides an efficient framework to count and classify invariants in tensor models of (gauge) symmetry G d = U(N 1) ⊗ · · · ⊗ U(N d ) . We show that there are two natural ways of counting invariants, one for arbitrary G d and another

On orthogonal p-adic wavelet bases

open access: yesJournal of Mathematical Analysis and Applications, 2015
A variety of different orthogonal wavelet bases has been found in L_2(R) for the last three decades. It appeared that similar constructions also exist for functions defined on some other algebraic structures, such as the Cantor and Vilenkin groups and local fields of positive characteristic.

Hilbert Bases for Orthogonal Arrays [PDF]

open access: yesJournal of Statistical Theory and Practice, 2007
In this paper, we relate the problem of generating all 2-level orthogonal arrays of given dimension and force, i.e. elements in OA$(n,m)$, where $n$ is the number of factors and $m$ the force, to the solution of an Integer Programming problem involving rational convex cones. We do not restrict the number of points in the array, i.e. we admit any number

Constructing Mutually Unbiased Bases from Quantum Latin Squares [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2017
We introduce orthogonal quantum Latin squares, which restrict to traditional orthogonal Latin squares, and investigate their application in quantum information science.

Discrete orthogonal transforms with bases generated by self-similar sequences [PDF]

open access: yesКомпьютерная оптика, 2018
New bases of discrete orthogonal transforms associated with some recursive processes and possessing a property of self-similarity are introduced and investigated in the paper.
