Robert John Aumann

Robert John Aumann is a German-born Israeli mathematician and economist who was awarded the 2005 Nobel Memorial Prize in Economic Sciences for his work on conflict and cooperation through game-theory analysis. He is a professor at the Center for the Study of Rationality at the Hebrew University of Jerusalem in Israel.

Aumann’s work has focused on game theory, which is the study of decision-making in strategic situations. He has made significant contributions to the field of cooperative game theory, which deals with how groups of individuals can achieve collective goals through cooperation. He also developed the concept of correlated equilibrium, which is a solution concept for non-cooperative games that generalizes the well-known Nash equilibrium.

Aumann has also applied game theory to the study of conflict and cooperation in international relations, particularly in relation to issues of security and diplomacy. He has also made contributions to the study of repeated games, which are games that are played multiple times, and to the study of decision-making under uncertainty.

Aumann’s work has had a significant impact on the fields of economics, political science, and computer science, and his ideas have been applied to a wide range of real-world problems.
