Abstract

we give criteria for when a valuation of a skewfield F is also a valuation of the Dickson nearfield F^κ which is derived from F by the coupling K on F. For the construction of examples, a rational function field F = K (t) is given. The set (v) of all prolongations of a valuation u on AT to F is well known. Sufficient conditions are given which guarantee that couplings κ on F and elements ω ε (u) are in this sense compatible so that ω is a valuation of the Dickson nearfield F^κ. Examples demonstrate the results.
