This book is dedicated to modern approaches to mathematical modeling of reflexive processes in control. The authors consider reflexive games that describe the gametheoretical interaction of agents making decisions based on a hierarchy of beliefs regarding (1) essential parameters (informational reflexion) (2) decision principles used by opponents (strategic reflexion) (3) beliefs about beliefs and so on. Informational and reflexive equilibria in reflexive games generalize a series of well-known equilibrium concepts in noncooperative games and models of collective behavior. These models allow posing and solving the problems of informational and reflexive control in organizational economic social and other systems in military applications etc. (the interested reader will find in the book over 30 examples of possible applications in these fields) and describing uniformly many psychological/sociological phenomena connected with reflexion viz. implicit control informational control via the mass media reflexion in chess art works etc. The present book is intended for experts in decision making and control of systems of an interdisciplinary nature as well as for undergraduates and postgraduates. .
