## To be or not to be Yutsis: Algorithms for the decision problem

Van Dyck, D; Brinkmann, Gunnar; Fack, Veerle; McKay, Brendan

### Description

Generalized recoupling coefficients or 3nj-coefficients can be expressed as multiple sums over products of Racah or 6j-coefficients [L.C. Biedenharn, J.D. Louck, Coupling of n angular momenta: recoupling theory, in: The Racah-Wigner Algebra in Quantum Theory, Encyclopedia of Mathematics and its Applications, vol. 9, Addison-Wesley, 1981, pp. 435-481]. The problem of finding an optimal summation formula (i.e. with a minimal number of Racah coefficients) for a given 3nj-coefficient is equivalent...[Show more]
