Abstract
The Grothendieck-Katz -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 -curvature vanishes modulo , for almost all primes . We prove that if the variety is a generic curve, then every simple closed loop on the curve has finite monodromy.
