In this paper we introduce a new style of drawing a plane graph G, called proper Ε½ . box rectangular PBR drawing. It is defined to be a drawing of G such that every vertex is drawn as a rectangle, called a box, each edge is drawn as either a horizontal or a vertical line segment, and each face is dr

## Abstract In this paper, necessary and sufficient conditions are derived for the existence of a common quadraβtic Lyapunov function for a finite number of stable second order linear timeβinvariant systems. Copyright Β© 2002 John Wiley & Sons, Ltd.
A general formulation for discrete-time quantum mechanics, based on Feynman's method in ordinary quantum mechanics, is presented. It is shown that the ambiguities present in ordinary quantum mechanics (due to noncommutativity of the operators), are no longer present here. Then the criteria for the u
