Abstract: Kazhdan and Lusztig showed that every topologically nilpotent, regular semisimple orbit in the Lie algebra of a simple, split group over the field $\mathbb{C}(\negthinspace(t)\negthinspace)$ is, in some sense, close to a regular nilpotent orbit. We generalize this result to a setting that includes most quasisplit $p$-adic groups.
