Games with incomplete information

With its clear notions and problem setting theory of games can rightly be considered a unified mathematical discipline. Viewed in itself it can hardly be criticized on its merits. Yet, things are quite different if we look upon the background it originated from and examine its practical applicability, too. This is indispensable since there is a growing demand for mathematical tools capable of serving various sciences in a similar way they did mainly for physics in the past. Recently numerous new fields of mathematics have emerged which beside supplying methods for solving actual problems of certain sciences (such as physics, chemistry, biology, sociology etc.) aim at giving assistance to formulate their basic notions and relations in an exact way. Thereby the spectrum of applications of mathematics has broadened a great deal. Mathematical systems theory, for instance, has also been developing in this spirit.
