DESCRIPTION:Title: <a href="https://researchseminars.org/talk/OSGA/101/">M
 etric differentiation and embeddings of the Heisenberg group</a>\nby Rober
 t Young (New York University) as part of Online Seminar "Geometric Analysi
 s"\n\n\nAbstract\nThe Heisenberg group is the simplest example of a noncom
 mutative nilpotent Lie group. In this talk\, we will explore how that nonc
 ommutativity affects geometry and analysis in the Heisenberg group. We wil
 l describe why good embeddings of $\\mathbb{H}$ must be bumpy at many scal
 es\, how to study embeddings into $L_1$ by studying surfaces in $\\mathbb{
 H}$\, and how to construct a metric space which embeds into $L_1$ and $L_4
 $ but not in $L_2$. This talk is joint work with Assaf Naor.\n
