In many fields, equilibria or stability are fundamental concepts that can be described in terms of fixed points. Some examples follow. • In projective geometry, a fixed point of a projectivity has been called a double point. • In economics, a Nash equilibrium of a game is a fixed point of the game's best response correspondence. John Nash exploited the Kakutani fixed-point theorem for his seminal paper that won him the Nobel pr… WebIn mathematics, Anderson acceleration, also called Anderson mixing, is a method for the acceleration of the convergence rate of fixed-point iterations. Introduced by Donald G. Anderson,[1]this technique can be used to find the solution to fixed point equations f(x)=x{\displaystyle f(x)=x}often arising in the field of computational science.
