Combining cusped triangle groups with Blaschke products: commensurable matings

Yusheng Luo, Mahan Mj, Sabyasachi Mukherjee

In this note, we construct algebraic correspondences as matings of Fuchsian -triangle groups with Blaschke products. Combined with the results of [MM25], this proves…

Universality of the Basilica

Yusheng Luo, Mahan Mj, Sabyasachi Mukherjee

We establish universality of the fat Basilica Julia set in conformal dynamics in the following sense: is quasiconformally equivalent to the fat Ba…

Teichmüller spaces, polynomial loci, and degeneration in spaces of algebraic correspondences

Yusheng Luo, Mahan Mj, Sabyasachi Mukherjee

We develop an analog of the notion of a character variety in the context of algebraic correspondences. It turns out that matings of certain Fuchsian groups and polynomials are cont…

Landing rays and ray Cannon-Thurston maps

Rakesh Halder, Mahan Mj, Pranab Sardar

In this paper, we describe a procedure to construct pairs of hyperbolic groups with the following properties. 1) Every geodesic ray in converges to a point $ξ_γ\in \p…

Simultaneous Uniformization and Algebraic Correspondences

Mahan Mj, Sabyasachi Mukherjee

We prove a generalization of Bers' simultaneous uniformization theorem in the world of algebraic correspondences. More precisely, we construct algebraic correspondences that simult…

Tight contact structures on hyperbolic homology 3-spheres

Mahan Mj, Balarka Sen

We produce a large class of hyperbolic homology 3-spheres admitting arbitrarily many distinct tight contact structures. We also produce a sub-class admitting arbitrarily many disti…

Cubulating Drilled bundles over graphs

Mahan Mj, Biswajit Nag

We start with a Gromov-hyperbolic surface bundle over a graph, and drill out essential simple closed curves from fibers to obtain a drilled bundle . We prove that for such d…

Indiscrete Common Commensurators

Jingyin Huang, Mahan Mj

We develop a framework for common commensurators of discrete subgroups of lattices in isometry groups of CAT(0) spaces. We show that the Greenberg-Shalom hypothesis about discreten…
