While the theory of Lie groups is highly developed in characteristic 0, comparatively little is known about analytic groups over local fields of positive characteristic p. More generally, one can consider groups which are analytic over pro-p domains R, without restricting the Krull dimension to 1. Natural examples are rings of the form R =
p[t1,...,tm].
Experience shows that analytic pro-p groups, also in this general sense, possess interesting properties, and one faces the challenge of developing a systematic structure theory for such objects. With this long-term goal in mind, we collect several fundamental results which provide information about the structure of R-analytic pro-p groups. In particular, we establish a useful criterion for isolating
p[t]-analytic groups within the class of finitely generated pro-p groups.
