Throughout the years, Nash equilibrium has had a most\nsignificant impact in economics and many other areas. However, more than 60\nyears later, its dynamic foundations - how are equilibria reached in long-term\ninteractions - are still not well established.\u003C\/p\u003E\n\n\u003Cp\u003E\u0026nbsp;In\nthis talk we will overview a body of work of the last decade on dynamical\nsystems in multi-player environments.\u0026nbsp; On\nthe one hand, the natural informational restriction that each participant may\nnot know the payoffs and utilities of the other participants -\n\u0022uncoupledness\u0022 - turns out to severely limit the possibilities to\nconverge to Nash equilibria.\u0026nbsp; On the\nother hand, there are simple adaptive heuristics - such as \u0022regret\nmatching\u0022 - that lead in the long run to correlated equilibria, a concept\nthat embodies full rationality. We will also mention connections to behavioral\nand neurobiological studies, to computer science concepts, and to engineering\napplications.\u003C\/p\u003E\n\n\u003Cp\u003E\u0026nbsp;Biography\u003C\/p\u003E\n\n\u003Cp\u003ESergiu\nHart is the Kusiel-Vorreuter University Professor, Professor of Mathematics,\nand Professor of Economics, at the Hebrew University of Jerusalem. From 1991 to\n1998 he was the founding director of the highly reputed Center for the Study of\nRationality.\u003C\/p\u003E\n\n\u003Cp\u003EBesides\ngame theory and economic theory, he has contributions in mathematics, computer\nscience, probability and statistics. He is known for studies of strategic\nfoundations of cooperation; strategic use of information in long-term interactions\n(\u0022repeated games\u0022); adaptive and evolutionary dynamics, particularly\nwith boundedly rational agents; perfect economic competition and its relations\nto models of fair distribution; and riskiness.\u003C\/p\u003E\n\n\u003Cp\u003EHe\nis Fellow of the Econometric Society and Member of the Israel Academy of\nSciences and Humanities. In 1998 he received the Rothschild Prize. He served as\npresident of the Israel Mathematical Union in 2005-2006, and as president of\nthe Game Theory Society in 2008-2010. \u003C\/p\u003E\n\n\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"\u201cGame Dynamics and Equilibria\u201d"}],"uid":"27466","created_gmt":"2012-02-20 12:00:16","changed_gmt":"2016-10-08 01:58:05","author":"Dani Denton","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2012-03-01T15:30:00-05:00","event_time_end":"2012-03-01T16:30:00-05:00","event_time_end_last":"2012-03-01T16:30:00-05:00","gmt_time_start":"2012-03-01 20:30:00","gmt_time_end":"2012-03-01 21:30:00","gmt_time_end_last":"2012-03-01 21:30:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"47223","name":"College of Computing"},{"id":"50875","name":"School of Computer Science"}],"categories":[],"keywords":[],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1795","name":"Seminar\/Lecture\/Colloquium"}],"invited_audience":[],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cp\u003E\u003Ca href=\u0022mailto:denton@cc.gatech.edu\u0022\u003Edenton@cc.gatech.edu\u003C\/a\u003E\u003C\/p\u003E","format":"limited_html"}],"email":[],"slides":[],"orientation":[],"userdata":""}}}
