OverviewExcerpt from Dispersion Relations and the Abstract Approach to Field Theory Furthermore it is assumed that it is possible to define a vacuum state: that is the energy operator should possess a smallest eigenvalue which we normalize to zero. The knowledge of commutation relations for field Operators is almost not necessary. Equation 1) is sufficient. Now we want to examine the vacuum expectation values of quadratic field magnitudes. As the orthogonal system in Hilbert space we shall use in this case, the eigenvectors of the PM operators, which should form a complete set.
