We show that there is a residual subsetRofDiff1(M)such that for anyf is an element of Rand anypartially hyperbolic homoclinic classH(p,f)with one-dimensional central direction, theset of central Lyapunov exponents associated with the ergodic measure with either full supportor positive entropy is an interval.
