• #### Upper bounds for the number of solutions to quartic thue equations ﻿

[OWP-2011-21] (Mathematisches Forschungsinstitut Oberwolfach, 2011)
We will give upper bounds for the number of integral solutions to quartic Thue equations. Our main tool here is a logarithmic curve $\phi(x,y)$ that allows us to use the theory of linear forms in logarithms. This manuscript ...
• #### The Weyl group of the Curtz algebra ﻿

[OWP-2011-31] (Mathematisches Forschungsinstitut Oberwolfach, 2011-05-28)
The Weyl group of the Cuntz algebra $\mathcal{O}_n$ is investigated. This is (isomorphic to) the group of polynomial automorphisms $\lambda_u$ of $\mathcal{O}_n$, namely those induced by unitaries u that can be written ...
