Bradley Delso, Margarita (1990) An elementary based sufficient condition for sums of 2mth powers of polynomials over non-archimedean real closed fields. Journal of Pure and Applied Algebra , 63 (3). pp. 219-224. ISSN 0022-4049
Using some model-theoretic arguments applied to the theory of real valuations, we obtain a sufficient condition based on elementary properties of , K any real closed field, for ƒ to be sum of 2mth powers of rational functions in K(x).
