Chernousov–Rapinchuk finiteness conjecture for forms of algebraic groups

Let K=k(C)K=k(C) be the function field of a smooth affine geometrically integral curve over a field kk, and let VV be the set of discrete valuations associated with the closed points of CC. Let GG be an absolutely almost simple simply connected algebraic KK-group, and let mm be the order of the automorphism group of its root system. Assume that chark\operatorname{char} k is prime to mm and that kk satisfies (Fm)(F_m'). A KK-form of GG is said to have good reduction at vVv\in V when it has good reduction at the valuation vv. Chernousov–Rapinchuk finiteness conjecture. The set of KK-isomorphism classes of KK-forms of GG that have good reduction at all vVv\in V is finite. This conjecture extends known finiteness results for spinor groups and special unitary groups to all absolutely almost simple simply connected algebraic groups under the stated assumptions; its general validity remains open.
