Mathematical Instantons in Characteristic Two
Published online by Cambridge University Press: 04 December 2007
Abstract
On P$^3$, we show that mathematical instantons in characteristic two are unobstructed. We produce upper bounds for the dimension of the moduli space of stable rank two bundles on P$^3$ in characteristic two. In cases where there is a phenomenon of good reduction modulo two, these give similar results in characteristic zero. We also give an example of a nonreduced component of the moduli space in characteristic two.
