Nonboldfaced

In order to avoid confusion later, we shall here use non'''boldfaced letters to denote these interaction representation quantities which, as stated, are really free-field Heisenberg representation quantities.

Nonboldfaced variables denote scalars

The points of ℍⁿ, ℍ⃰ⁿ, and Γ will be denoted by the nonboldfaced letters, unlike the generic points in 𝔼^(n,1).
