Gustav Feichtinger is a Professor Emeritus of Operations Research at the Vienna University of Technology (TU Wien). Moreover, he is Research Group Leader for Population Economics at the Vienna Institute of Demography of the Austrian Academy of Sciences. He is a Corresponding Member of the academy and holds an Honorary Doctorate from the Otto von Guericke University of Magdeburg. His main interests are in the economic applications of optimal control theory, dynamic games and nonlinear dynamical systems, as well as population mathematics. Raimund Kovacevic is currently an Assistant Professor (Univ. Ass.) at the TU Wien’s Institute of Statistics and Mathematical Methods in Economics. His main research areas are stochastic optimization, stochastic control, optimization with PDE constraints, and bilevel optimization with applications in energy, finance and insurance. He has worked as an Assistant Professor at Vienna University and as a risk manager and consultant.Gernot Tragleris currently an Associate Professor for Operations Research and Dean of Academic Affairs for Technical Mathematics, both at the TU Wien. His research focuses on Operations Research and mathematical methods in economics, including various methods of nonlinear and dynamic optimization, chiefly as applied to socio-economic processes and problems of energy supply and the environment. He has supervised more than fifty Master’s and Ph.D. theses and teaches several courses at the graduate level.
