Exponential Formulas for the Jacobians and Jacobian Matrices of Analytic Maps

Wenhua Zhao

Let $F = (F_{1}, F_{2}, ... F_{n})$ be an $n$ -tuple of formal power series in $n$ variables of the form $F (z) = z + O (∣ z ∣^{2})$ . It is known that there exists a unique formal differential opera…

D-log and formal flow for analytic isomorphisms of n-space

David Wright, Wenhua Zhao

Given a formal map $F = (F_{1} ..., F_{n})$ of the form $z + higher$ order terms, we give tree expansion formulas and associated algorithms for the D-Log of F and the formal flow F_t.…
