A power law with respect to length n is numerically observed in the off-diagonalterm of the one-particle Green's function g,.,..(E ) (7': energy, /: lattice site) and in theresistance ran, E) and conductance g(n, E) of a Fibonacci lattice. The exponent isinsensitive to energy, and the power law crosses over an exponential law at a lengthn'(E ) = l / A (E ), where A (E ) is a Lyapunov exponent which is strongly energy-sensiLive. As a result, power law conductivity and resistivity with respect to temperatureT are expected to be observed over a suitable range of temperatures.
