Abstract: Extending the results obtained in [1] we have proved the existence and the uniqueness of entropy solutions to ultra-parabolic equations with initial, boundary and, correspondingly, impulsive conditions. The case without impulsive conditions has been treated in [2,3].The main challenge of the Cauchy-Dirichlet problem being under our study is that boundary conditions are formulated as inequalities.
