On the geometry of nilpotent orbits
Webp-adic Hodge structure analogous to the complex case. We show that any nilpotent orbit in the period domain of Hodge-Tate structures convergesto a semistable point (filtration) in the period domain of the p-adic Hodge structure. Furthermore, the nilpotent orbits of the limit point are asymptotic to the twisted period map [Theorem 3.2]. WebJared. 30.9k 10 57 137. 6. Fun fact: the equation A n = 0 defines some ideal in the polynomial algebra on n 2 variables. So does the equation ch ( A) = A n where ch is the characteristic polynomial, which also describes nilpotent matrices. These are not the same ideal! (Although their radicals are the same.) – Qiaochu Yuan.

WebFor example, these orbits have a linear ordering with respect to the closure relation, and $ K_{\mathbb C} $ acts on them in multiplicity-free manner. We clarify the $ K_{\mathbb C} $ -module structure of the regular function ring of the closure of these nilpotent orbits in detail, and prove the normality.
