Abstract
The directed polymer on disordered hierarchical lattices is studied us ing an exact renormalization scheme. The phase transition is studied a nd a hyperscaling relation is derived. The fixed distributions of the renormalized energies are obtained numerically. The specific heat and associated exponents are computed from the fixed distributions.
