Conjugation coinvariants of quantum matrices
... induces an action of GL(N, C) on the coordinate algebra C[X ij ] of N × N matrices. The
invariant functions with respect to this action are well-known, they are the elements in the
C-subalgebra of C[Xij ] that is generated by the trace functions σi , for i = 1, . . . , N, where
σi is the sum of the ...
