Solvable flow

A flow on a solv manifold determined by the action on of some one-parameter subgroup of the solvable Lie group : If consists of the cosets , then under the action of the solvable flow such a coset goes to the coset at time . A particular case of a solvable flow is a nil-flow; in the general case the properties of a solvable flow can be considerably more diverse.

Comments

In many cases dynamical properties of the flow, such as ergodicity, can be deduced from algebraic properties of and . The Kronecker theorem implies ergodicity for the case , , the integer lattice, and the flow (written additively) given by , where is a coset of and is a fixed vector whose components are linearly independent over the rational numbers. When and is a discrete subgroup, certain one-parameter subgroups of correspond to geodesic and horocycle flow (cf. Geodesic flow; Horocycle flow) on unit tangent bundles of surfaces of constant negative curvature (cf. Constant curvature, space of).
