Generalized Principle of limiting 4-dimensional symmetry.Relativistic   length expansion in accelerated system revisited
  In this article, Generalized Principle of "limiting 4-dimensional symmetry": The laws of physics in non-inertial frames must display the 4-dimensional symmetry of the Generalized Lorentz-Poincare group in the limit of zero acceleration,is proposed.Classical solution of the relativistic length expansion in general accelerated system revisited.
