We consider conductivities of two-dimensional lattice electrons in a magnetic field. We focus onsystems where the flux per plaquette</>is irrational (incommensurate flux). To realize the systemwith the incommensurate flux, we consider a series of systems with commensurate fluxes whichconverge to the irrational value. We have calculated a real part of the longitudinal conductivitycr..(;). Using a scaling analysis, we have found Ra..(cu) behaves as X/r;' (7 : 0.55) when</>: r, (r : "?) and the Fermi energy is near zero. This behavior is closely related to theknown scaling behavior of the spectrum.
