Square-well potential by an algebraic approach

Physical Review A, 1986
The spectrum-generating algebra for the problem of a particle in a potential well is shown to be su(1,1). Both the infinitely deep and finite square wells are considered. The generators can also be derived via a systematic procedure for determining the time-dependent constants of the motion. The coherent states are explicitly constructed.

An Algebraic Construction for Room Squares

SIAM Journal on Applied Mathematics, 1972
The generalized singular direct product for quasi-groups is used to prove the following theorem: If there are pairs of Room quasi-groups of orders v, q and p, such that the pair of order p is a Room pair of subquasi-groups of the pair of order q and $q - p \ne 6$, then there is a pair of Room quasi-groups of order $v( {q - p} ) + p$. This theorem gives

Reducible Spectral Theory with Applications to the Robustness of Matrices in Max-Algebra

SIAM Journal on Matrix Analysis and Applications, 2009
Let $a\oplus b=\max(a,b)$ and $a\otimes b=a+b$ for $a,b\in\overline{\mathbb{R}}:=\mathbb{R}\cup\{-\infty\}$. By max-algebra we understand the analogue of linear algebra developed for the pair of operations $(\oplus,\otimes)$, extended to matrices and ...

An Algebraic Treatment of Magic Squares

The Mathematics Teacher, 1973
Magic squares have always served as a good motivation device for drill in elementary and junior high mathematics. This article will consider an algebraic treatment of the 3×3 magic square to show some algebraic activities that can be carried out by the beginning or the advanced algebra student.
