Présentation

Michel THERA is a professor emeritus of mathematics in the laboratory XLIM from the University of Limoges. He also has been in charge of the research group on optimisation and Vice-President of the university. His research focuses on variational analysis, convex analysis, continuous optimization, monotone operator theory and the interaction among these fields of research, and their applications. He has published more than 110 articles in international journals. He serves as editor for several journals on continuous optimization and has been responsible for several international research programs until his retirement. He is now Professor Emeritus from the University of Limoges and Adjunct professor from Federation University (Australia).
