Valuation theoretic methods in the birational geometry of algebraic varieties
Stefan Günther
In this paper, we give a valuation formula for rational top differential forms of function fields in characteristic zero for arbitrary Abhyankar places generalizing the classical v…

Valuation Theory, Riemann Varieties and the Structure of integral Preschemes
Stefan Günther
In this work we show that the classical subject of general valuation theory and Zariski-Riemann varieties has a much wider scope than commutative algebra and desingularization theo…

A Short Note on Polynomial Automorphisms
Stefan Günther
In this paper, we construct explicitely polynomial automorphisms of affine n-space for certain n. More precisely, we construct algebraic subgroups of the general polynomial group G…
