Limit cycles for successive projections onto hyperplanes in imagen Original Research Article

In this paper we consider successive orthogonal projections onto m hyperplanes in imagen, where m greater-or-equal, slanted 2 and n greater-or-equal, slanted 2. A limit cycle is defined to be a sequence of points formed by projecting onto each of the hyperplanes once in a prescribed order, with the last projection giving the starting point. Several examples, including triangles, quadrilaterals, regular polygons, and arbitrary collections of lines in image2, are solved for the limit cycle. Limit cycles are found in various ways, including by a limiting process and by solving an mn × mn linear system of equations. The latter approach will produce all the limit cycles for an arbitrary ordered set of m hyperplanes in imagen.
