On New Notions of Orthogonality in Normed Spaces via the 2-HH-Norms [PDF]

open access: yes, 2009
Kikianty and Dragomir in 2008 introduced the p-HH-norms on the Cartesian product of two copies of a normed space, which are equivalent to the well-known p-norms. In this paper, notions of orthogonality in terms of 2-HH-norms are introduced.

Monomiality, orthogonal and pseudo-orthogonal polynomials [PDF]

open access: yesInternational Mathematical Forum, 2006
We reconsider some families of orthogonal polynomials, within the framework of the so called monomiality principle. We show that the associated operational formalism allows the framing of the polynomial orthogonality using an algebraic point of view. Within such a frame- work, we introduce families of pseudo-orthogonal polynomials, namely polynomials,

Matrix interpretation of multiple orthogonality [PDF]

open access: yes, 2010
In this work we give an interpretation of a (s(d + 1) + 1)-term recurrence relation in terms of type II multiple orthogonal polynomials.We rewrite this recurrence relation in matrix form and we obtain a three-term recurrence relation for vector ...

Orthogonality and Dimensionality [PDF]

open access: yesAxioms, 2013
In this article, we present what we believe to be a simple way to motivate the use of Hilbert spaces in quantum mechanics. To achieve this, we study the way the notion of dimension can, at a very primitive level, be defined as the cardinality of a maximal collection of mutually orthogonal elements (which, for instance, can be seen as spatial directions)

Scaling for orthogonality

open access: yesIEEE Transactions on Signal Processing, 1993
The accumulated product of orthogonal matrices gradually departs from orthogonality, due to rounding errors. An attractive remedy for this problem, because of its simplicity, consists in renormalizing the columns (scaling) after each partial product.

A New Approximate Birkhoff Orthogonality Type

open access: yesEuropean Journal of Mathematical Analysis, 2022
In this note, we introduce a new approximate Birkhoff orthogonality type and give a characterization for inner product spaces using the approximate orthogonality.
