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…

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…
