MUNM127 Теория на игрите и динамичните системи (SECS...S/06)
Анотация:
The course aims to define and apply some mathematical methods and tools, in particular the theory of dynamical systems and the theory of games, to model the time evolution of social and economic systems. The systems considered are often adaptive systems, influenced by the presence of boundedly rationa, heterogeneous and interacting agents. Some lessons will be devoted to a deeper analysis of some mathematical concepts already introduced in the framework of the course in General Mathematics in order to use them in more advanced applications. The formal methods studied in this course will give a general understanding of the setup of a mathematical model in economics and how the results obtained should be critically analyzed. This is obtained both through the analysis of some models given in the literature and by examples and exercises proposed in classrooom notes.
At the end of the course the students should be able to built and analyze mathematical models expressed by the formalism of dynamical systems and/or the theory of games, and a sufficient capability of using mathematical and logical tools to describe in a schematic way the behaviour of complex situations. These mathematical tools should enhance the approach towards the description and the management of time evolving complex economic systems, and favour the ability to interface with experts in mathematics and computer science in order to study the behaviour of economic systems by an interdisciplinary approach.
