Limit sets of unfolding paths in Outer space
Mladen Bestvina, Radhika Gupta, Jing Tao
We construct an unfolding path in Outer space which does not converge in the boundary, and instead it accumulates on the entire 1-simplex of projectivized length measures on a non-…
Orientable maps and polynomial invariants of free-by-cyclic groups
Spencer Dowdall, Radhika Gupta, Samuel J. Taylor
We relate the McMullen polynomial of a free-by-cyclic group to its Alexander polynomial. To do so, we introduce the notion of an orientable fully irreducible outer automorphism …
Planar lattice subsets with minimal vertex boundary
Radhika Gupta, Ivan Levcovitz, Alexander Margolis +1
A subset of vertices of a graph is minimal if, within all subsets of the same size, its vertex boundary is minimal. We give a complete, geometric characterization of minimal sets f…
Groups acting on CAT(0) cube complexes with uniform exponential growth
Radhika Gupta, Kasia Jankiewicz, Thomas Ng
We study uniform exponential growth of groups acting on CAT(0) cube complexes. We show that groups acting without global fixed points on CAT(0) square complexes either have uniform…
Hierarchically hyperbolic groups and uniform exponential growth
Carolyn Abbott, Thomas Ng, Davide Spriano +2
We give several sufficient conditions for uniform exponential growth in the setting of virtually torsion-free hierarchically hyperbolic groups. For example, any hierarchically hype…
Cannon--Thurston maps for CAT(0) groups with isolated flats
Benjamin Beeker, Matthew Cordes, Giles Gardam +2
Mahan Mitra (Mj) proved Cannon--Thurston maps exist for normal hyperbolic subgroups of a hyperbolic group. We prove that Cannon--Thurston maps do not exist for infinite normal hype…
Loxodromic elements in the cyclic splitting complex and their centralizers
Radhika Gupta, Derrick Wigglesworth
We show that an outer automorphism acts loxodromically on the cyclic splitting complex if and only if it has a filling lamination and no generic leaf of the lamination is carried b…
Loxodromic elements for the relative free factor complex
Radhika Gupta
In this paper we prove that a fully irreducible outer automorphism relative to a non-exceptional free factor system acts loxodromically on the relative free factor complex as defin…
Relative Currents
Radhika Gupta
In this paper we define currents relative to a free factor system. We prove that a fully irreducible outer automorphism relative to a free factor system acts with uniform north-sou…
