Abstract

The antisymmetric square of the adjoint representation of any simple Lie algebra is equal to the sum of adjoint and X2X_2 representations. We present universal formulae for quantum dimensions of an arbitrary Cartan power of X2X_2. They are analyzed for singular cases and permuted universal Vogel's parameters. X2X_2 has been the only representation in the decomposition of the square of the adjoint with unknown universal series. Application to universal knot polynomials is discussed.
