Nilpotent Conjugacy Classes in $p$-adic Lie Algebras: The Odd Orthogonal Case
Published online by Cambridge University Press: 20 November 2018
Abstract
We will study the following question: Are nilpotent conjugacy classes of reductive Lie algebras over $p$-adic fields definable? By definable, we mean definable by a formula in Pas's language. In this language, there are no field extensions and no uniformisers. Using Waldspurger's parametrization, we answer in the affirmative in the case of special orthogonal Lie algebras $\mathfrak{s}\mathfrak{o}\left( n \right)$ for $n$ odd, over $p$-adic fields.
