Equations at infinity for critical-orbit-relation families of rational maps

Rohini Ramadas, Rob Silversmith

We develop techniques for using compactifications of Hurwitz spaces to study families of rational maps $P^{1} \to P^{1}$ defined by critical orbit relations. We apply t…

Pullbacks of $κ$ classes on $M_{0, n}$

Rohini Ramadas

The moduli space $M_{0, n}$ carries a codimension- $d$ cycle class $κ_{d}$ . We consider the subspace $K_{n}^{d}$ of $A^d(\overline{\mathcal{M}}_{0,n},\…

Two-dimensional cycle classes on $M_{0, n}$

Rohini Ramadas, Rob Silversmith

For each $n \geq 5$ , we give an $S_{n}$ -equivariant basis for $H_{4} (M_{0, n}, Q)$ , as well as for $H_{2 (n - 5)} (M_{0, n}, Q)$ . Such…

Post-Critically Finite Maps on $P^{n}$ for $n \geq 2$ are Sparse

Patrick Ingram, Rohini Ramadas, Joseph H. Silverman

Let $f : P^{n} \to P^{n}$ be a morphism of degree $d \geq 2$ . The map $f$ is said to be post-critically finite (PCF) if there exist integers $k \geq 1$ and $ℓ \geq 0$ such th…

Dynamical invariants of monomial correspondences

Nguyen-Bac Dang, Rohini Ramadas

We focus on various dynamical invariants associated to toric correspondences, using algebraic geometry or arithmetic. We find a formula for the dynamical degrees, relate the expone…

Algebraic stability of meromorphic maps descended from Thurston's pullback maps

Rohini Ramadas

Let $ϕ : S^{2} \to S^{2}$ be an orientation-preserving branched covering whose post-critical set has finite cardinality $n$ . If $ϕ$ has a fully ramified periodic point $p_{\infty}$ and s…
