The $p$-curvature conjecture and monodromy about simple closed loops

Ananth Shankar


The Grothendieck-Katz p-curvature conjecture is an analogue of the Hasse Principle for differential equations. It states that a set of arithmetic differential equations on a variety has finite monodromy if its p-curvature vanishes modulo p, for almost all primes p. We discuss this conjecture in the case of families, and in particular, prove that if the variety is a generic curve, then every simple closed loop has finite monodromy.
