Abstract

Let kk be an algebraic closure of a finite field of odd characteristic. We prove that for any rank two graded Higgs bundle with maximal Higgs field over a generic hyperbolic curve X1X_1 defined over kk, there exists a lifting XX of the curve to the ring W(k)W(k) of Witt vectors as well as a lifting of the Higgs bundle to a periodic Higgs bundle over X/WX/W. As a consequence, it gives rise to a two-dimensional absolutely irreducible representation of the arithmetic fundamental group π1(XK)\pi_1(X_K) of the generic fiber of XX. This curve XX and its associated representation is in close relation with the canonical curve and its associated canonical crystalline representation in the pp-adic Teichm\"{u}ller theory for curves due to S. Mochizuki. Our result may be viewed as an analogue of the Hitchin-Simpson's uniformization theory of hyperbolic Riemann surfaces via Higgs bundles.
