Quadratic Phase Multiresolution Analysis and the Construction of Orthonormal Wavelets in L2(ℝ)

open access: yesAxioms, 2023
The multi-resolution analysis (MRA) associated with quadratic phase Fourier transform (QPFT) serves as a tool to construct orthogonal bases of the L2(R). Consequently, it assumes a pivotal role in facilitating potential applications of QPFT.

Orthogonal Bases for Vertex-Mapped Pyramids [PDF]

open access: yesSIAM Journal on Scientific Computing, 2016
Discontinuous Galerkin (DG) methods discretized under the method of lines must handle the inverse of a block diagonal mass matrix at each time step. Efficient implementations of the DG method hinge upon inexpensive and low-memory techniques for the inversion of each dense mass matrix block.

Orthogonal bases in specific generalized symmetry classes of tensors [PDF]

open access: yesJournal of Mahani Mathematical Research
Let $V$ be a unitary vector space. Suppose $G$ is a permutation group of degree $m$ and $\Lambda$ is an irreducible unitary representation of $G$. We denote by $V_{\Lambda}(G)$ the generalized symmetry class of tensors associated with $G$ and $\Lambda ...

Strong quantum nonlocality and unextendibility without entanglement in $N$-partite systems with odd $N$ [PDF]

open access: yesQuantum
A set of orthogonal product states is strongly nonlocal if it is locally irreducible in every bipartition, which shows the phenomenon of strong quantum nonlocality without entanglement.

INTERPOLATING WAVELETS ON THE SPHERE

open access: yesUral Mathematical Journal, 2019
There are several works where bases of wavelets on the sphere (mainly orthogonal and wavelet-like bases) were constructed. In all such constructions, the authors seek to preserve the most important properties of classical wavelets including constructions

Application of the Algebraic Extension Method to the Construction of Orthogonal Bases for Partial Digital Convolutions

open access: yesAlgorithms
Mathematical tools have been developed that are analogous to the tool that allows one to reduce the description of linear systems in terms of convolution operations to a description in terms of amplitude-frequency characteristics.

Numeric-analytical approach to integrals calculation at construction of orthogonal models

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2009
The numeric-analytical method of calculation of the integrals is proposed for construction of orthogonal models. The given method allows to increase the accuracy of orthogonal models due to obtained algebraic and recurrent relations for integrals used ...
