Abhyankar's Inertia Conjecture for Some Sporadic Groups

Dean Bisogno

This paper verifies Abhyankar's Inertia Conjecture for certain sporadic groups $G$ in particular characteristics by showing that all possible inertia groups occur for $G$ -Galois co…

Group-theoretic Johnson classes and a non-hyperelliptic curve with torsion Ceresa class

Dean Bisogno, Wanlin Li, Daniel Litt +1

Let l be a prime and G a pro-l group with torsion-free abelianization. We produce group-theoretic analogues of the Johnson/Morita cocycle for G -- in the case of surface groups, th…

The Supersingularity of Hurwitz Curves

Dean Bisogno, Erin Dawson, Henry Frauenhoff +5

We study when Hurwitz curves are supersingular. Specifically, we show that the curve $H_{n, ℓ} : X^{n} Y^{ℓ} + Y^{n} Z^{ℓ} + Z^{n} X^{ℓ} = 0$ , with $n$ and $ℓ$ relatively prime, is s…
