Jul3 reviewed Reviewed Idempotents in a local ring Jul3 comment Idempotents in a local ring Welcome to math.stackexchange. You may want to give some idea of what the Jacobian is, and why being in the Jacobian implies that $1-e$ is invertible. Jul3 reviewed No Action Needed Distribution of integer solution pairs (x,y) for $2x^2 = y^2 + y$ Jul2 comment Should I use the minus sign when writing papers in characteristic two This is what I had been largely doing (though I am not sure how consciously). But you wouldn't find it unusual either way?
