Cutting Polygons Composed of Equal Rectangles into Similar Rectangles
Mathematical Notes, 2021\textit{M. Dehn} [Math. Ann. 57, 314--332 (1903; JFM 34.0547.02)] proved his famous result that a rectangle can be cut into squares if and only if the ratio of the sides of the rectangle is a rational number. One can consider the general and very complicated problem of cutting a polygon into similar rectangles.

Magic rectangles and modular magic rectangles
Journal of Statistical Planning and Inference, 1996A magic \(( m, n)\) rectangle is an \(m\times n\) matrix with entries \(1,\dots, mn\) for which all the row sums are the same and all the column sums are the same. A modular magic \((m, n)\) rectangle is an \(m\times n\) matrix with entries \(1,\dots, mn\) for which all the row sums are congruent modulo \(mn\) and all the column sums are congruent ...

Let R be a rectangle with given area a(R), height h(R) and width w(R), and r1, r2, …, rn be n soft rectangles, where we mean by a soft rectangle a rectangle r whose area a(r) is prescribed but whose aspect ratio ρ(r) is allowed to be changed. In this paper, we consider the problem of packing n soft rectangles r1, r2, …, rn into R.

There are a number of communications problems involving two-dimensional arrays with constrained correlation functions. Golomb's two classes of radar arrays and sonar arrays are examined. Improved bounds, optimal cases, and computational procedures are reported.
