Non-zero constant Jacobian polynomial maps of ²

Nguyen Van Chau (1999)

Annales Polonici Mathematici

Similarity:

We study the behavior at infinity of non-zero constant Jacobian polynomial maps f = (P,Q) in ℂ² by analyzing the influence of the Jacobian condition on the structure of Newton-Puiseux expansions of branches at infinity of level sets of the components. One of the results obtained states that the Jacobian conjecture in ℂ² is true if the Jacobian condition ensures that the restriction of Q to the curve P = 0 has only one pole.

Thomas’ conjecture over function fields

Volker Ziegler (2007)

Journal de Théorie des Nombres de Bordeaux

Similarity:

Thomas’ conjecture is, given monic polynomials p 1 , ... , p d [ a ] with 0 < deg p 1 < < deg p d , then the Thue equation (over the rational integers) ( X - p 1 ( a ) Y ) ( X - p d ( a ) Y ) + Y d = 1 has only trivial solutions, provided a a 0 with effective computable a 0 . We consider a function field analogue of Thomas’ conjecture in case of degree d = 3 . Moreover we find a counterexample to Thomas’ conjecture for d = 3 .

Computation of 2-groups of positive classes of exceptional number fields

Jean-François Jaulent, Sebastian Pauli, Michael E. Pohst, Florence Soriano–Gafiuk (2008)

Journal de Théorie des Nombres de Bordeaux

Similarity:

We present an algorithm for computing the 2-group 𝒞 F p o s of the positive divisor classes in case the number field F has exceptional dyadic places. As an application, we compute the 2-rank of the wild kernel W K 2 ( F ) in K 2 ( F ) .

Jung's type theorem for polynomial transformations of ℂ²

Sławomir Kołodziej (1991)

Annales Polonici Mathematici

Similarity:

We prove that among counterexamples to the Jacobian Conjecture, if there are any, we can find one of lowest degree, the coordinates of which have the form x m y n + terms of degree < m+n.
