Abstract

We construct embeddings Yn,τHilbn(Στ)\mathcal{Y}_{n,\tau} \to {Hilb}^n (\Sigma_{\tau}) for each of the classical Lie algebras \gersp2m(\Cc)\ger{sp}_{2m}(\Cc), \gerso2m(\Cc)\ger{so}_{2m}(\Cc), and \gerso2m+1(\Cc)\ger{so}_{2m+1}(\Cc). The space Yn,τ\mathcal{Y}_{n,\tau} is the fiber over a point τ\gerh/W\tau \in \ger h / W of the restriction of the adjoint quotient map χ:\gerg\gerh/W\chi : \ger g \to \ger h /W to a suitably chosen transverse slice of a nilpotent orbit. These embeddings were discovered for \gersl2m(\Cc)\ger{sl}_{2m}(\Cc) by Ciprian Manolescu. They are related to the symplectic link homology of Seidel and Smith.
