On the Image Conjecture
Arno van den Essen, David Wright, Wenhua Zhao
The Image Conjecture was formulated by the third author, who showed that it implied his Vanishing Conjecture, which is equivalent to the famous Jacobian Conjecture. We prove variou…
Images of Locally Finite Derivations of Polynomial Algebras in Two Variables
Arno van den Essen, David Wright, Wenhua Zhao
In this paper we show that the image of any locally finite -derivation of the polynomial algebra in two variables over a field of characteristic zero is a Mathieu…
The Jacobian Conjecture as a problem in combinatorics
David Wright
The Jacobian Conjecture has been reduced to the symmetric homogeneous case. In this paper we give an inversion formula for the symmetric case and relate it to a combinatoric struct…
A New Approach to Order Polynomials of Labeled Posets and Their Generalizations
John Shareshian, David Wright, Wenhua Zhao
In this paper, we first give formulas for the order polynomial $Ω(\Pw; t)$ and the Eulerian polynomial $e(\Pw; λ)$ of a finite labeled poset using the adjacency matrix of…
D-log and formal flow for analytic isomorphisms of n-space
David Wright, Wenhua Zhao
Given a formal map of the form order terms, we give tree expansion formulas and associated algorithms for the D-Log of F and the formal flow F_t.…
