Let $p\_1, p\_2, \ldots$, be the power sum symmetric functions. Let $p\_n^\* = n \frac{\partial}{\partial p\_n}$. Then $$ p\_n^\* p\_m - p\_m p\_n^\* = \delta\_{m, n} 1. $$
Where could I find this result in some books or papers? Thank you very much.

This is also in his book on Hilbert schemes of points in chapter 8.
