Description
We give explicit index-free formulae for all the degree 6 (and also degree 4 and 2) algebraically independent local unitary invariant polynomials for finite-dimensional k-partite pure and mixed quantum states. We carry this out using graph-technical methods, which provide illustrations for this abstract topic. (paper)
