Abstract

Let KK be an unramified pp-adic local field and let WW be the ring of integers of KK. Let (X,S)/W(X,S)/W be a smooth proper scheme together with a simple normal crossings divisor and fix positive integers rr and ff. We show that the set of absolutely irreducible representations π1(XKˉ)GLr(Zpf)\pi_1(X_{\bar K})\rightarrow \mathrm{GL}_r(\mathbb{Z}_{p^f}) that come from log crystalline Zpf\mathbb Z_{p^f}-local systems over (XK,SK)(X_K,S_K) of rank rr is finite. The proof uses pp-adic nonabelian Hodge theory and a finiteness result due Abe/Lafforgue.
