It is shown in particular that a straightforward refinement of Tuy\u0027s earlier topological minimax theorems can be obtained that yields several new minimax theorems with much weaker compactness and continuity assumptions than usual. An application to Lagrange relaxation is given that provides a rigorous foundation for decomposition methods in nonconvex global optimization.\n\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"Minimax Theorems: Old and New","format":"limited_html"}],"field_summary_sentence":[{"value":"ISyE Guest Lecturer:  Hoang Tuy"}],"uid":"27216","created_gmt":"2009-10-12 21:22:55","changed_gmt":"2016-10-08 01:48:27","author":"Ruth Gregory","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2007-03-06T10:00:00-05:00","event_time_end":"2007-03-06T11:00:00-05:00","event_time_end_last":"2007-03-06T11:00:00-05:00","gmt_time_start":"2007-03-06 15:00:00","gmt_time_end":"2007-03-06 16:00:00","gmt_time_end_last":"2007-03-06 16:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"1242","name":"School of Industrial and Systems Engineering (ISYE)"}],"categories":[],"keywords":[{"id":"6401","name":"Hoang Tuy"},{"id":"6393","name":"ISyE Guest Lecturer"}],"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":"\u003Cstrong\u003EFaiz Al-Khayyal\u003C\/strong\u003E\u003Cbr \/\u003EISyE\u003Cbr \/\u003E\u003Ca href=\u0022mailto:faiz.alkhayyal@isye.gatech.edu\u0022\u003EContact Faiz Al-Khayyal\u003C\/a\u003E\u003Cbr \/\u003E\u003Cstrong\u003E404-894-2300\u003C\/strong\u003E","format":"limited_html"}],"email":[],"slides":[],"orientation":[],"userdata":""}}}
