  Totally symmetric arbitrary spin fields in AdS space, conformal fields,
conformal currents, and shadow fields in flat space are studied. Light-cone
formulation for such fields, currents, and shadows is obtained. Use of the
Poincare parametrization of AdS space allows us to treat fields in flat and AdS
spaces on equal footing. Light-cone gauge realization of relativistic
symmetries for fields, currents, and shadows is also obtained. The light-cone
formulation for fields is obtained by using the gauge invariant Lagrangian
which is presented in terms of the modified de Donder divergence, while the
light-cone formulation for currents and shadows is obtained by using gauge
invariant approach to currents and shadows. This allows us to demonstrate
explicitly how ladder operators entering the gauge invariant formulation of
fields, currents, and shadows manifest themselves in the light-cone formulation
for fields, currents, and shadows.
