Project description

We characterize the class of linear algebraic groups over local rings via an action on an infinite tree. We generalize the theory of Moufang sets to an axiomatic theory determining those groups. Moreover, we study the normal subgroups of those groups. Each ideal of a local ring gives rise to such a normal subgroup, and the question is whether every normal subgroup arises in this fashion.
