Number Theory Seminar

Title: Constructing bounded orbits in homogeneous space
Speaker: Anurag Rao (Shanghai Institute for Mathematics and Interdisciplinary Sciences, China)
Date: 28 January 2026
Time: 11 am
Venue: LH-1, Mathematics Department (Joint with the APRG Seminar)

Consider a noncompact homogeneous space equipped with the action of a one-parameter diagonalizable subgroup. In this dynamical system we study the set of points with precompact orbit which, due to the work of Kleinbock–Margulis, is known to be a dense set of full dimension. Motivated by a theorem of Davenport–Schmidt in Diophantine approximation we revisit this work and give a construction for bounded orbits with large closures.
