Generic stability conjecture for definable groups over valuation rings
Generic stability conjecture for definable groups over valuation rings
Let be the valuation ring of a field with residue map , and let be a -definable group. Write for the smallest type-definable subgroup of bounded index, and let denote the space of types on over . For a type , let be its image under the residue map. Generic stability conjecture. (i) is generically stable. (ii) is a finite-index subgroup of . (iii) If is generically stable, then is dominated by . This conjecture extends the preceding results for linear algebraic groups over , such as and . It predicts generic stability, finite index of the connected component, and residue domination for arbitrary -definable groups of this form; the supplied text does not state a resolution.
