Iterated Cartier Flux and Non-Finite Generation of Tame Polynomial Automorphism Groups over Finite Fields

Stefan Barańczuk, Tomasz Ślusarski

Let k=Fq​ be a finite field of characteristic p, and let \[ U_n(k)=\{F\in\operatorname{TA}_n(k):F(0)=0,\ JF(0)=I_n\}. \] We prove that every special tame polynomial aut…

Prescribed extension spectra of mock automorphisms over finite fields

Stefan Barańczuk, Tomasz Ślusarski

We classify the finite-extension permutation spectra occurring in an explicit family of mock automorphisms over finite fields. Every finite nonempty divisor-closed subset of $\N_{>…

Reducing the number of equations defining a subset of the n-space over a finite field

Stefan Barańczuk

Let f1​,…,fk​ be polynomials defining an algebraic set in affine n-space over a finite field. Suppose k>n. We prove that there exists a system of polynomials $g_{1…
