Hyperbolic spaces with geometric and geometrically finite quasi-actions are symmetric
Daniel Groves, Emily Stark, Genevieve S. Walsh +1
We prove that if a proper metric space is quasi-isometric to a finitely generated group and to a space with a horoball over a finitely generated group, then that space is quasi-iso…
Quasi-Isometric Embeddings of Symmetric Spaces
David Fisher, Kevin Whyte
We prove a rigidity theorem that shows that, under many circumstances, quasi-isometric embeddings of equal rank, higher rank symmetric spaces are close to isometric embeddings. We…
Coarse Bundles
Kevin Whyte
We develop a coarse notion of bundle and use it to understand the coarse geometry of group extensions and, more generally, groups acting on proper metric spaces. The results are pa…
Twisted Inflation
Joshua L. Davis, Thomas S. Levi, Mark Van Raamsdonk +1
We present a new mechanism for slow-roll inflation based on higher dimensional supersymmetric gauge theory compactified to four dimensions with twisted (supersymmetry breaking) bou…
Baryon charge from embedding topology and a continuous meson spectrum in a new holographic gauge theory
Mark Van Raamsdonk, Kevin Whyte
We study a new holographic gauge theory based on probe D4-branes in the background dual to D4-branes on a circle with antiperiodic boundary conditions for fermions. Field theory co…
Coarse differentiation of quasi-isometries II: Rigidity for Sol and Lamplighter groups
Alex Eskin, David Fisher, Kevin Whyte
In this paper, which is the continuation of [EFW2], we complete the proof of the quasi-isometric rigidity of Sol and the lamplighter groups. The results were announced in [EFW1].
