I'm trying to understand the Chow-Rashevsky Theorem. I unfortunately do not have a formal knowledge of what's going on but have figured out most of the terms. Basically a system Σ must satisfy the Chow condition: L i e ( X 1, …, X m) ( q) = T q M, ∀ q ∈ M. where M is a manifold. But I cannot find a definition for T q. http://math.stanford.edu/~conrad/papers/Kktrace.pdf shivagrico implements limited

WebChow's Theorem [3] If H and D(H) are non-singular, then ϕ(P(H, x 0)) is the maximal connected integral submanifold of D(H) that passes through x 0. We proceed to restate this result in forms suggesting generalizations to more general path systems.

An analytic subvariety is defined as one that is locally the vanishing set of some holomorphic functions. So, if an embedded complex manifold is indeed analytic, then Chow's theorem shows it is algebraic. My problem is that I cannot see why this is necessarily true.

In mathematics, Chow's theorem may refer to a number of theorems due to Wei-Liang Chow: • Chow's theorem: The theorem that asserts that any analytic subvariety in projective space is actually algebraic. • Chow–Rashevskii theorem: In sub-Riemannian geometry, the theorem that asserts that any two points are connected by a horizontal curve.
