Wall representations of rectangular dissections: additional results
This paper shows that a wall representation, <I>W<sub>n</sub></I>, uniquely defines a geometrically meaningful relation between any two spaces contained in it. The set of such relations is called an <I>orthogonal structure</I>; it is realized by any <nobr>T-plan</nobr> <I>G<sub>n</sub></I> belonging to <I>C</I>(<I>W<sub>n</sub></I>).
