Explore infinite-horizon difference games governed by difference equations or inequalities in this 55-minute webinar presented by Naila Hayek from Université Panthéon-Assas, Paris II, France. Delve into various Nash-equilibrium concepts and examine Pontryagin maximum principles in both strong and weak forms as necessary conditions for Nash equilibrium. Learn about the tools used for reduction to finite horizon and conditions related to infinite horizon. Investigate special cases, including bounded processes and asymptotical constraints, utilizing optimization techniques in Banach spaces to derive necessary conditions for Nash equilibrium. Gain insights into sufficient conditions for these games, enhancing your understanding of dynamic game theory and its applications.
