Nature of problem: Explicit construction of SO(5) ⊃ SO(3) spherical harmonics on S4. Evaluation of SO(3)-reduced matrix elements and SO(5) ⊃ SO(3) Clebsch-Gordan coefficients (isoscalar factors). | ||
Solution method: Construction of SO(5) ⊃ SO(3) spherical harmonics by orthonormalization, obtained from a generating set of functions, according to the method [1]. Matrix elements and Clebsch-Gordan coefficients follow by construction and integration of SO(3) scalar products. | ||
Running time: Depends strongly on the maximum SO(5) and SO(3) representation labels involved. A few minutes for the calculation in the Mathematica notebook. | ||
