Vladimir Lefebvre
Vladimir Alexandrovich Lefebvre (Влади́мир Алекса́ндрович Лефе́вр, 22 September 1936 in Leningrad, USSR – 9 April 2020) was a mathematical psychology, mathematical psychologist at the University of California, Irvine. With his wife, V. I. Dubovskaya, Lefebvre left USSR for USA in 1974. He created equations to predict the large-scale consequences of individual actions. Among the parameters in the equations are the self image of the individual and the action as perceived via this self-image. The result is a number expressing the probability that the individual in question will perform a specific action. Lefebvre's mathematical approach to social psychology is often referred to as reflexive control, reflexive theory - presumably due to the 'reflexive' nature of taking into account subjects' self-image(s). Lefebvre developed Reflexive Theory as a military researcher in the former Soviet Union, where he was born and educated prior to coming to the United ...

Game Theory
Game theory is the study of mathematical models of strategic interactions. It has applications in many fields of social science, and is used extensively in economics, logic, systems science and computer science. Initially, game theory addressed two-person zero-sum games, in which a participant's gains or losses are exactly balanced by the losses and gains of the other participant. In the 1950s, it was extended to the study of non zero-sum games, and was eventually applied to a wide range of Human behavior, behavioral relations. It is now an umbrella term for the science of rational Decision-making, decision making in humans, animals, and computers. Modern game theory began with the idea of mixed-strategy equilibria in two-person zero-sum games and its proof by John von Neumann. Von Neumann's original proof used the Brouwer fixed-point theorem on continuous mappings into compact convex sets, which became a standard method in game theory and mathematical economics. His paper was f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
