Among work undertaken after this was work on the representation of rational functions as sums of squares, integral points on certain elliptic curves, Kummer sums, and on factorising polynomials in several variables.
Sa trabaho matapos ang nagtangka na ito ay gumagana sa representasyon ng katuwiran function bilang sums ng squares, mahalaga na puntos sa ilang tambilugin kurva, Kummer sums, at sa factorising polynomials sa ilang mga variable.
