  We investigate by means of Monte Carlo simulations the dynamic phase
transition of the two-dimensional kinetic Blume-Capel model under a
periodically oscillating magnetic field in the presence of a quenched random
crystal-field coupling. We analyze the universality principles of this dynamic
transition for various values of the crystal-field coupling at the originally
second-order regime of the corresponding equilibrium phase diagram of the
model. A detailed finite-size scaling analysis indicates that the observed
nonequilibrium phase transition belongs to the universality class of the
equilibrium Ising ferromagnet with additional logarithmic corrections in the
scaling behavior of the heat capacity. Our results are in agreement with
earlier works on kinetic Ising models.
