Description:
Letℝbe the real number axis. Suppose thatG,HareCmmaps fromℝ2n+3toℝ. In this note, we discuss the system of finite difference equationsG(x,f(x),f(x+1),…,f(x+n),g(x),g(x+1),…,g(x+n))+0andH(x,g(x),g(x+1),…,g(x+n),f(x),f(x+1),…,f(x+n))=0for allx∈ℝ, and give some relatively weak conditions for the above system of equations to have uniqueCmsolutions(m≥0).
