The relationship between game theory and mathematics!

Game theory actually belongs to a branch of mathematics, but its application in economics is more visible. Nash, the founder of game theory, is a pure mathematician. In 195 1, he gave the definition of Nash game equilibrium and the proof of its existence. The existence of Nash equilibrium is the basis of non-cooperative game. Judging from the originality of mathematics and the difficulty of proof, this theorem is not too difficult, but it is only the application of the fixed point theorem in mathematics, but it has become the most fundamental basis of game theory, making game theory one of the most important analytical tools in economics, which has a wide range of applications in economics, and it can be used to study the strategic choice of interaction between economic people.
