S_3-covers of schemes
Robert W. Easton
We analyze flat S_3-covers, attempting to create structures parallel to those found in the abelian theory. We use an initial local analysis as a guide in finding a global descripti…

Absolute Galois acts faithfully on the components of the moduli space of surfaces: A Belyi-type theorem in higher dimension
Robert W. Easton, Ravi Vakil
Given an object over the algebraic closure Qbar of Q, there is often no reason for invariants of the corresponding holomorphic object to be preserved by the absolute Galois group G…

Surfaces Violating Bogomolov-Miyaoka-Yau in Positive Characteristic
Robert Easton
The Bogomolov-Miyaoka-Yau inequality asserts that the Chern numbers of a surface X of general type in characteristic 0 satisfy the inequality c_1^2 <= 3c_2, a consequence of which…
