In 1990s Vogel introduced an interesting parametrisation of simple Lie
algebras by 3 parameters defined up to common multiple and permutations.
Numerical characteristic of Lie algebra is universal if it can be expressed
rationally in terms of Vogel’s parameters (example – dimension of Lie
algebra). I will present new universal formulae for certain Casimir
eigenvalues as well as for some quantities in ChernSimons theory on a 3D
sphere, found jointly with Mkrtchyan and Sergeev.
