Classification of Table Algebras with Two Basis Elements Whose Product Is a Linear Combination of Their Conjugates

open access: closedAlgebra Colloquium, 2006
Table Algebras (A,B) with distinct non-real basis elements a, b∈ B satisfying [Formula: see text], (m, n∈ ℝ+) are studied in this paper. The two cases where either a is real and b is non-real or a, b are both real were completely classified by Arad and Blau. Here, we study the remaining case where a and b are non-real.

On the linear algebra of generalized doubly stochastic matrices and their equivalence relations and permutation basis

open access: closedJapan Journal of Applied Mathematics, 1986
A generalized doubly stochastic matrix is an \(n\times n\) matrix such that each row and column sum is equal to a given \(x\neq 0\) in a field F, where char (F)\(\nmid n\). \(J_ n\) is the \(n\times n\) matrix such that if e is the unit in F and if n is also used to denote the n-fold sum \(e+e+...+e\), then every entry in \(J_ n\) is \(n^{-1 ...

A linear algebraic algorithm for reducing the support size of t-designs and to generate a basis for trades

open access: closedCommunications in Statistics - Simulation and Computation, 1987
A simple linear algebraic algorithm to generate a basis of the null space of a given integral matrix is utilized to present a computer algorithm, which in general, is used to reduce the support size of a given design as in a theorem of FoodyHedayat (Theorem 4.1, 1977), and in particular, it is used to produce a basis for trades.

Conjugacy Analysis of the Finite-Difference Equations of the Method of Characteristics on the Basis of a Linear-Algebraic Formulation

open access: closedAtomic Energy, 2017
A linear-algebraic form of the equations of the method of characteristics, which is used to approximate the neutron transport equation, is obtained. It is shown on the basis of the obtained linear-algebraic form that the discrete form of the conjugate equation differs from the algebraically discrete problem constructed by linear-algebraic ...

Numerical Linear Algebra

Fundamentals of Numerical Mathematics for Physicists and Engineers, 2020
Given some m×m matrix A, suppose we reduce A to Hessenberg form H by an orthogonal matrix Q. Then, AQ = QH. Let Qn be the matrix composed of the first n columns of Q.
