  The nonequilibrium dynamic phase transition, in the kinetic Ising model in
presence of an oscillating magnetic field, has been studied by Monte Carlo
simulation. The fluctuation of dynamic order parameter has been studied as a
function of temperature near the dynamic transition point. The temperature
variation of appropriately defined `susceptibility' has also been studied near
the dynamic transition point. Similarly, fluctuation of energy and
appropriately defined `specific-heat' have been studied as a function of
temperature near the dynamic transition point. In both the cases, the
fluctuations (of dynamic order parameter and energy) and the corresponding
responses diverge (as power law fashion) near the dynamic transition point with
similar critical behavior (with identical exponent values).
