  The generalized parton distributions (GPDs) for the spin-3/2 $\Delta^+$
resonance are studied numerically by using a diquark spectator approach. Our
results show that symmetric constraints from time reversal on GPDs are
satisfied. The axial vector form factors of the system are also provided and
compared with the lattice QCD calculation. Furthermore, the structure functions
are obtained from GPDs in the forward limit. The evolution of structure
functions to the scales up to 4 GeV are carried out as predictions for the
possible lattice QCD calculations.
