Robert Aumann
contemporaryGame Theory / Epistemic Logicb. 1930
Robert Aumann is an Israeli-American mathematician and game theorist who shared the 2005 Nobel Memorial Prize in Economic Sciences for his work on conflict and cooperation through game-theory analysis. He is best known for developing the theory of repeated games and for his agreement theorem, which formalizes when rational agents with common knowledge cannot 'agree to disagree.' His work bridges mathematics, economics, and epistemic logic, with significant influence on philosophical discussions of rationality and common knowledge.
