Query: Dynamic quantum theory of large additional dimensions for non-massive
  particles   Brane model of universe is considered for zero-mass particle. Equation of
Wheeler - de Witt type is obtained using variation principle from the
well-known conservation laws inside the brane. This equation includes term
accounting the variation of brane topology. Solutions are obtained analytically
at some simplifications and the dispersion relations are derived for frequency
of wave associated with the particle.
