Badness and non-stationarity for dfg groups
Badness and non-stationarity for dfg groups
Let be a group definable in an -minimal structure or a -adically closed field, and assume that is a group. Say that is bad when it has the badness property defined in the paper, namely the relevant strongly -generic behavior fails as specified there. Badness conjecture. The group is bad if and only if is non-stationary. The paper has established badness for the displayed examples of the additive square and the Borel subgroup, while the equivalence for arbitrary groups in the stated classes remains open.
