✦ Synopsis


We present a characterization of the maximal compatible extensions of a given compatible partial order ≤ r on a unary algebra (A,f ). These extensions can be constructed by using the compatible linear extensions of ≤ r*, where (A*,f*) is the so called contracted quotient algebra of (A,f) and the compatible partial order ≤ r* on (A*,f*) is naturally induced by ≤ r. Using this characterization, we determine the intersection of the maximal compatible extensions of ≤ r.

The interior of an orthogonal polygon drawn on a regular grid of the plane defines a set of cells (or squares) called a polyomino. We prove that the intersection graph of the maximal rectangles contained in a polyomino is slightly triangulated or has a star cutset.
