Russian Academy of Sciences Ural Branch, Institute of Mathematics and Mechanics of the Ural Branch of the Russian Academy of Sciences, Ural State University International Seminar "Control Theory and Theory of Generalized Solutions of Hamilton-Jacobi Equations" (CGS'2005) Dedicated to the 60th Anniversary of Academician Andrei Izmailovich Subbotin (16.02.1945-14.10.1997) Ekaterinburg, Russia, June 22-25, 2005 http://cgs.imm.uran.ru Academician A.I.Subbotin (February 16, 1945 - October 14, 1997) is an outstanding specialist in the area of mechanics and control processes. He made a major contribution to developing the mathematical theory of optimal guaranteed control of dynamic systems. A.I.Subbotin was one of the founders of the theory of positional differential games. He suggested the concept and developed the theory of minimax (generalized) solutions of first-order PDEs. The theory has sources in and is applied to problems of optimal guaranteed control. Topics of the International Seminar are connected with the main scientific areas of investigation of dynamic systems, in which A.I.Subbotin worked: mathematical theory of optimal control, differential game theory, theory of generalized solutions of Hamilton-Jacobi equations and their applications to practical problems. These branches are being elaborated in Ekaterinburg at the Institute of Mathematics and Mechanics (Ural Branch of the Russian Academy of Sceinces) and at the Ural State University. The seminar will take place in the sanatorium "Zelyony mys" which is 70 km far from Ekaterinburg (Yekaterinburg). The city of Ekaterinburg is one of the largest administrative, industrial, cultural, and scientific centers of Russia. It is located in a picturesque area of the Urals close to the border between Europe and Asia. Scopes of the seminar include the following topics. Generalized solutions of Hamilton-Jacobi equations Control of dynamic systems under conditions of conflict and uncertainty Problems of estimation and identification in dynamic systems Inverse problems and distributed control systems. Numerical algorithms for constructing solutions of optimal control problems and boundary value problems for Hamilton-Jacobi equations. The seminar program is expected to include plenary reports (45 minutes) and session presentations (15 minutes). Publication of abstracts and proceedings of the seminar is being planned. For participation it is necessary not later than March 1, 2005 to send by e-mail to the Organizing Committee cgs05@imm.uran.ru a filled registration form and a visa-form. Blanks of registration and visa-forms and detailed rules for submitting abstracts are disposed on the seminar web-site http://cgs.imm.uran.ru.

The First International Conference “Inverse Problems: Modeling and Simulation” July 14-21, 2002, Fethiye, Turkey The International Conference “Inverse Problems: Modeling and Simulation” will be held during July 14-21, 2002, in the historic city of Fethiye on the Mediterranean Sea, in Turkey. The main aim of the Conference is to promote unity through diversity and to encourage worldwide interest in the theory and applications of inverse problems. Our forum is going to bring together about 300 leading scientists from many different countries and many speciality applications. The proposed International Conference will be under the auspices of such international journals as Inverse Problems, Inverse Problems in Engineering, Inverse and Ill-Posed Problems, and Computational Methods in Applied Mathematics. The Conference will be very wide and attract leading American, Asian, and European scientists. “Inverse Problems: Modeling and Simulation” Abstracts - Instructions
