I was recommended a book by Oort sometime ago to read with reference to deformation theory, in particular in positive characteristic with hyperelliptic curves.
I couldn't find anything that seemed to be that relevant, I wondered if anyone would know what the book was?
Also, any general advice regarding deformation theory books would be much appreciated.
Thank you in advance.
Mumford's Lectures on curves on an algebraic surface is a wonderful book, which develops ideas related to deformation theory (especially embedded deformations, as part of the infinitesimal theory of Hilbert schemes), and many other fundamental topics in algebraic geometry.
