Nov 12, 2021 at 21:46 comment added Pulcinella Thank you for this. I just have a couple of questions: a. do you have a reference for the definitions of slope of an ODE and of a sheaf, and b. do you have any reference for this notion of deformation of a sheaf which uses both the ring of coeffients and the base?
