Gabor orthogonal bases and convexity [PDF]
Gabor orthogonal bases and convexity, Discrete Analysis 2018:19, 11 pp. A fundamental way of understanding a function $f$ defined on $\mathbb R^d$ is to expand it in terms of a basis with nice properties.

A new description of orthogonal bases [PDF]
We show that an orthogonal basis for a finite-dimensional Hilbert space can be equivalently characterised as a commutative †-Frobenius monoid in the category FdHilb, which has finite-dimensional Hilbert spaces as objects and continuous linear maps as morphisms, and tensor product for the monoidal structure.

Trace-orthogonal normal bases [PDF]
For \(q\) a prime power and \(n\geq 2\) an integer, let \(GF(q^ n)\) denote the finite field of order \(q^ n\) considered as a vector space of dimension \(n\) over \(GF(q)\). For \(\alpha\in GF(q^ n)\), a basis of the form \((\alpha, \alpha^ q,\cdots, \alpha^{q^{n-1}})\) is called a normal basis of \(GF(q^ n)\) over \(GF(q)\).

Homeomorphic Images of Orthogonal Bases [PDF]
Necessary and sufficient conditions are obtained for a sequence $\{x_j:~j\in \mathbb J\}$ in a Hilbert space to be, up to the elimination of a finite subset of $\mathbb J$, the linear homeomorphic image of an orthogonal basis of some Hilbert space $K$. This extends a similar result for orthonormal bases due to Holub [J.R. Holub.

On the Orthogonal Bases of Symmetry Classes [PDF]
Let \(V\) be an \(n\)-dimensional complex inner product space and let \(\{e_1,\dots,e_n\}\) be an orthonormal basis of \(V\). Suppose \(G\) is a permutation group of degree \(m\) and \(X\) is an irreducible character of \(G\). The symmetry class of tensors associated with \(G\) and \(X\) is denoted by \(V_X(G)\).

On scalar products in higher rank quantum separation of variables
Using the framework of the quantum separation of variables (SoV) for higher rank quantum integrable lattice models [1], we introduce some foundations to go beyond the obtained complete transfer matrix spectrum description, and open the way to the ...

Curl-conforming hierarchical vector bases for triangles and tetrahedra [PDF]
A new family of hierarchical vector bases is proposed for triangles and tetrahedra. These functions span the curl-conforming reduced-gradient spaces of Nédélec.

Wavelets based on orthogonal polynomials [PDF]
We present a unified approach for the construction of polynomial wavelets. Our main tool is orthogonal polynomials. With the help of their properties we devise schemes for the construction of time localized polynomial bases on bounded and unbounded subsets of the real line. Several examples illustrate the new approach.

The problem of mutually unbiased bases in dimension 6 [PDF]
We outline a discretization approach to determine the maximal number of mutually unbiased bases in dimension 6. We describe the basic ideas and introduce the most important definitions to tackle this famous open problem which has been open for the ...
