Synchronization of a kind of financial chaotic systems on criteria of dominant matrix

A new chaos synchronization method is brought forward for a kind of financial chaotic systems. Using properties of row strictly diagonally dominant matrix and stability principle of differential equation, this method can turn chaos synchronization problem between driving chaotic system and response system into a criteria on determining a matrix which is row strictly diagonally dominant. This method need not use local Jacobian analysis, and also it need not construct Lyaponov function, it is a direct chaos synchronization method. Numeric simulations show effectiveness of this method.
