This paper presents geometrical foundation for a systematic treatment of three main (elliptic, parabolic and hyperbolic) types of analytic function theories based on the representation theory of SL 2 (R) group.We describe here geometries of corresponding domains.The principal rôle is played by Clifford algebras of matching types.In this paper we also generalise the Schwerdtfeger-Fillmore-Springer-Cnops construction which describes cycles as points in the extended space.This allows to consider many algebraic and geometric invariants of cycles within the Erlangen program approach.
