On the rigidity of certain Pham-Brieskorn rings

Michael Chitayat, Daniel Daigle

Fix a field $k$ of characteristic zero. If $a_{1}, ..., a_{n}$ ( $n > 2$ ) are positive integers, the integral domain $B = k [X_{1}, ..., X_{n}] / (X_{1}^{a_{1}} + ... + X_{n}^{a_{n}})$ is called a P…

Field generators in two variables and birational endomorphisms of $A^{2}$

Pierrette Cassou-Noguès, Daniel Daigle

This article is a survey of two subjects: the first part is devoted to field generators in two variables, and the second to birational endomorphisms of the affine plane. Each one o…

Locally nilpotent sets of derivations

Daniel Daigle

Let B be an algebra over a field k and let Der(B) be the set of k-derivations from B to B. We define what it means for a subset of Der(B) to be a locally nilpotent set. We prove so…
