Polynomial endomorphisms over finite fields: experimental results
Stefan Maubach, Roel Willems
Given a finite field $\F_q$ and , one could try to compute all polynomial endomorphisms $\F_q^n\lp \F_q^n$ up to a certain degree with a specific property. We consider t…
Analogue of the Duistermaat-van der Kallen Theorem for Group Algebras
Wenhua Zhao, Roel Willems
Let be a group, an integral domain, and the subspace of the group algebra consisting of all the elements of whose coefficient of the identity element $1…
Polynomial automorphisms over finite fields: Mimicking non-tame and tame maps by the Derksen group
Stefan Maubach, Roel Willems
If is a polynomial automorphism over a finite field $\F_q$ in dimension , then it induces a bijection of $(\F_{q^r})^n$ for every . We say that c…
Some Results on the Vanishing Conjecture of Differential Operators with Constant Coefficients
Arno van den Essen, Roel Willems, Wenhua Zhao
In this paper we prove four cases of the vanishing conjecture of differential operators with constant coefficients and also a conjecture on the Laurent polynomials with no holomorp…
