| Oct 25, 2022 at 2:23 | comment | added | Deepesh Singh | Thanks for your answer, Vladimir. Would you also know of any references or methods that talk about how to derive the 'non-polynomial' invariants of SU(n) then? For example, I'm interested in the L2 norm and the Bombeiri norm of the complex coefficients of my original symmetric and homogenous polynomials - which are also SU(n) invariant. These norms are polynomials in not just the coefficients but also their complex conjugates. I can't see how they can be expressed as linear combinations of the SL(n,C) invariants which are polynomials only in the coefficients but not their complex conjugates. | |
