On the uniform finite generation of SO(n, )

A Lie group G, generated by two one-parameter subgroups is said to be uniformly finitely generated by them if there exists a positive integer N such that every element of G can be expressed as a product of at most N elements chosen alternately from the two one-parameter subgroups. In this paper we construct pairs of generators of so(n) whose one-parameter subgroups uniformly finitely generate SO(n) and as a consequence, we put an upper bound on the number of switches required to join any two points on a manifold M trajectories of two particular vector fields on M.
