We derive the self-consistent relativistic Boltzmann-Uehling-Uhlenbeck (RBUU) equation for the delta distribution function within the framework which we have done for nucleon{close_quote}s. In our approach, the {Delta} isobars are treated in essentially the same way as nucleons. Both mean field and collision terms of {Delta}{close_quote}s RBUU equation are derived from the same effective Lagrangian and presented analytically. We calculate the in-medium {ital N}{Delta} elastic and inelastic scattering cross sections up to twice nuclear matter density and the results show that the in-medium cross sections deviate substantially from Cugnon{close_quote}s parametrization that is commonly used in the transport model. {copyright} {ital 1996 The American Physical Society.}
