One-relator Sasakian groups

Indranil Biswas, Mahan Mj

We prove that any one-relator group $G$ is the fundamental group of a compact Sasakian manifold if and only if $G$ is either finite cyclic or isomorphic to the fundamental group of…

Propagating quasiconvexity from fibers

Mahan Mj, Pranab Sardar

Let $1 \to K ⟶ G ⟶ π Q$ be an exact sequence of hyperbolic groups. Let $Q_{1} < Q$ be a quasiconvex subgroup and let $G_{1} = π^{- 1} (Q_{1})$ . Under rela…

Monodromy representations of meromorphic projective structures

Subhojoy Gupta, Mahan Mj

We determine the image of the monodromy map for meromorphic projective structures with poles of orders greater than two. This proves the analogue of a theorem of Gallo-Kapovich-Mar…

Meromorphic projective structures, grafting and the monodromy map

Subhojoy Gupta, Mahan Mj

A meromorphic projective structure on a punctured Riemann surface $X ∖ P$ is determined, after fixing a standard projective structure on $X$ , by a meromorphic quadratic diff…

Tight trees and model geometries of surface bundles over graphs

Mahan Mj

We generalize the notion of tight geodesics in the curve complex to tight trees. We then use tight trees to construct model geometries for certain surface bundles over graphs. This…

Cheeger inequalities for graph limits

Abhishek Khetan, Mahan Mj

We introduce notions of Cheeger constants for graphons and graphings. We prove Cheeger and Buser inequalities for these. On the way we prove co-area formulae for graphons and graph…
