摘要: The symmetries of the gradient free ultralocal model quantum field theories are studied. internal parameter λ introduced by J. R. Klauder is replaced an r‐component vector and used to obtain r‐vector operator φ. Then many‐body models with translational rotational symmetry set up partitioning into N, 3‐d ’’relative coordinates.’’ Hartree‐type 1/N limits studied in this found be accurate only if contributions from ‖χ‖≳≳0 negligible. A brief sketch given how produce more general UN pairing interaction models.
