Abstract
In this paper, we survey some topics and results of game theory which has been developing for last several decades, mainly in a field of economic theory. Topics and results are selected in the view of interests for scientists and engineers and can be understood without knowledge of economic theory since some reviews of game theory have already exists in economics. We discuss the interpretation of Nash equilibria and the concept of common knowledge. The concept of refinement for equilibria and some results of repeated games are reviewed. Finally, we intoroduce games with incomplete informati on.
