Descent for étale covers of proper regular models of elliptic curves
Okay let me try my hand at an answer. Specifically, I'll address the final question, which is whether there exists a unique descent of a geometrically connected finite etale connected cover $D_{\...

Non-degeneracy in hyperplane intersections of canonical curves
Edit: my answer contained an incomplete argument, here's a second attempt.
Assume by way of contradiction that for a generic hyperplane the expression $$
\begin{aligned}
D(p_1,\ldots,p_6)=\det (p_1 ...
