Classical field
WebEdit: the mode decomposition can be achieved in Classical Field Theory, the only thing is that the coefficients will be numbers. The equation of motion is $$(\Box + m^2)\phi=0$$ Take the Fourier transform in the spatial variable so that denoting the Fourier transform by $\hat{\phi}$ you have WebIn a classical field theory, the physical states are sections of a Poincaré-equivariant vector bundle over Minkowski space. The equivariance condition means that the group acts on the total space of the vector bundle, and the projection to Minkowski space is an equivariant map. Therefore, the Poincaré group also acts on the space of sections.
