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…

Transcendental correspondences: when Fuchsian groups take over basins of entire maps

Kostiantyn Drach, Sabyasachi Mukherjee, Leticia Pardo-Simón

In this paper, we initiate a systematic study of holomorphic correspondences that naturally arise as conformal combinations (matings) of transcendental entire m…

Mirrors of conformal dynamics: Interplay between anti-rational maps, reflection groups, Schwarz reflections, and correspondences

Mikhail Lyubich, Sabyasachi Mukherjee

The goal of this survey is to present intimate interactions between four branches of conformal dynamics: iterations of anti-rational maps, actions of Kleinian reflection groups, dy…

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…

Mating parabolic rational maps with Hecke groups

Shaun Bullett, Luna Lomonaco, Mikhail Lyubich +1

We prove that any degree rational map having a parabolic fixed point of multiplier with a fully invariant and simply connected immediate basin of attraction is mateable wit…

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…
