[3] The d-coefficients were introduced for SU (3), by M. Gell-Mann (réf. [1]) and Independently and for all SU (n), by L.C. Biedenharm, J. Math. Phys., vol. 4, 1963, p. 436.

[4] V.I. Ogievetskii and I.V. Polubarinov, This is the oldest paper listing essentially all relations between the f-and d-coefficients for SU (3) (Sov. J. Nucl. Phys., t. 4, 1967, p. 605).

L.M. Kaplan and M. Resnikoff, This paper gives a fairly complete set of relations for all SU (n) (J. of Math. Phys., t. 8, 1967, p. 2194.) After this paper several authors have discussed this type of relations : amongst the others we quote A. Pais, S.P. Rosen, A.J. Macfarlane, A. Subery and P.H. Weisz.

[5] C. Dublemond, This is to our knowledge the only paper where some relation are written in vector form (Ann. of Phys., t. 33, 1965, p. 214).

[6] A study of the invariants and their values for all representations is contained in A.M. Perelemov and V.S. Popov, Sov. J. Nucl. Phys., t. 3, 1966, p. 676, and in J.D. Louck and L.C. Biedenharn, J. Math. Phys., vol. 11, 1970, p. 2368.

[7] The concept of stratum used here is a simple example of that (« strate » in French) defined by R. Thom (L'Enseignement Mathématique, t. 8, 1962, p. 24). | Zbl 0109.40002
