Exactly solvable models showing chaotic behavior. II (Q914221)

In part I of this paper [ibid. 130, 597-605 (1985)] we reported several examples of one-dimensional mapping \((x_{n+1}=f(x_ n))\) which are exactly solvable and show chaotic behavior. We also explained the importance of the errors of the numerical calculation by comparing the exact solution with the numerical solution. In the present paper, we show several examples of two-dimensional mapping in which exact solutions are obtained, and the problem of the accuracy of the numerical calculation is mentioned again by showing examples.
