**invariant**quantities that may be formed from functions of the ten generators of the inhomogeneous Lorentz group . It should be noted that none of the invariants P_PH , WwWw , Pr , or Wz contain the coordinates X. Page

The little group that leaves p ,

The little group that leaves p ,

**invariant**is the three dimensional rotation group . For any fixed momentum component the operators wu are generators of the little group . Since w.P. = 0 , only three of the generators are linearly ...### What people are saying - Write a review
