Abstract
Let be a Brody-hyperbolic singular holomorphic foliation on a compact complex manifold . Suppose that has isolated singularities and that its Poincar\'e metric is complete. This is the case for a very large class of singularities, namely, non-degenerate and saddle-nodes in dimension . Let be an ergodic harmonic measure on . We show that the upper and lower local hyperbolic entropies of are leafwise constant almost everywhere. Moreover, we show that the entropy of is at least .
