Automorphisms of the fine grading of sl(n,C) associated with the generalized Pauli matrices

M. Havlíček, J. Patera, E. Pelantová +1

We consider the grading of $sl(n,\mathbb{C})$ by the group ${\Pi }_n$ of generalized Pauli matrices. The grading decomposes the Lie algebra into $n^2-1$ one--dimensional subspaces. In t…
