Abstract: | Explicit relations between two families of central
elements in the universal enveloping algebra $U(\frak{gl}_n)$ of
the general linear Lie algebra $\frak{gl}_n$ are presented.
The two families of central elements in question are
the ones expressed respectively by the determinants and the permanents:
the former are known as the Capelli elements,
and the latter are the central elements obtained by Nazarov.
The proofs given are based on the exactness of the
Koszul complex and the Euler-Poincaré principle. |
