2020. Jiaqi Bao, Ningyuan Yao Definably Topological Dynamics of p-Adic Algebraic Groups E-mail: Submission date: 11 July 2021 Abstract:
We study the p-adic algebraic groups G from the definable
topological-dynamical point of view. We consider the case that M is an
arbitrary p-adic closed field and G an algebraic group over ℚ_p
admitting an Iwasawa decompostion G=KB, where K is open and definably
compact over ℚ_p, and B is a borel subgroup of G over ℚ_p. Our main result is an explicit description of the minimal subflow and
Ellis Group of the universal definable G(M)-flow S_G(M^{ext}). We
prove that the Ellis group of S_G(M^{ext}) is isomorphic to the Ellis
group of S_B(M^{ext}), which is B/B^0. Mathematics Subject Classification: Keywords and phrases: |
