Abstract

We extend Henry Poincaré's normal form theory for autonomous difference equations xκ+1 = f(xκ) to nonautonomous difference equations xκ+1 = fκ(xκ). Poincaré's nonresonance condition λj - Πi=1n λiqi ≠ 0 for eigenvalues is generalized to the new nonresonance condition λj ∩ Πi=1n λiqi = Ø for spectral intervals.
