The Ponzano-Regge asymptotic of the supersymmetric 6jS symbols
Lionel Bréhamet
We adapt the Gurau's proof (2008) about the asymptotic limit of Ponzano-Regge formula to supersymmetric 6jS symbols according to their intrinsic parities alpha, beta, gamma. The be…
Regge symmetry and partition of Wigner 3-j or super 3-jS symbols: unknown properties
Lionel Bréhamet
For each generic $(3\mbox{-}j)$ the column parities, , define intrinsic parities: . In algebra only $(3\mbox{-}j)\_α$ exists whereas super-algebra $…
Remarks on the Egyptian 2/D table in favor of a global approach (D composite number)
Lionel Bréhamet
Egyptian decompositions of 2/D as a sum of two unit fractions are studied by means of certain divisors of D, namely r and s. Our analysis does not concern the method to find r and…
Remarks on the Egyptian 2/D table in favor of a global approach (D prime number)
Lionel Bréhamet
For h=3 or 4, Egyptian decompositions into h unit fractions, like 2/D = 1/D1 + ... +1/Dh, were given by using (h-1) divisors (di) of D1. This ancient modus operandi, well recognize…
