Editing Galois theory (section)

=== Aftermath ===
Galois' theory was notoriously difficult for his contemporaries to understand, especially to the level where they could expand on it. For example, in his 1846 commentary, Liouville completely missed the group-theoretic core of Galois' method.<ref name="Wussing2007">{{cite book|first=Hans|last=Wussing|title=The Genesis of the Abstract Group Concept: A Contribution to the History of the Origin of Abstract Group Theory|year=2007|publisher=Courier |isbn=978-0-486-45868-7|page=118}}</ref> [[Joseph Alfred Serret]] who attended some of Liouville's talks, included Galois' theory in his 1866 (third edition) of his textbook ''Cours d'algèbre supérieure''. Serret's pupil, [[Camille Jordan]], had an even better understanding reflected in his 1870 book ''Traité des substitutions et des équations algébriques''. Outside France, Galois' theory remained more obscure for a longer period. In Britain, [[Arthur Cayley|Cayley]] failed to grasp its depth and popular British algebra textbooks did not even mention Galois' theory until well after the turn of the century. In Germany, Kronecker's writings focused more on Abel's result. [[Richard Dedekind|Dedekind]] wrote little about Galois' theory, but lectured on it at Göttingen in 1858, showing a very good understanding.<ref name="Scharlau1981">{{cite book |first1=Winfried |last1=Scharlau |first2=Ilse |last2=Dedekind |first3=Richard |last3=Dedekind |title=Richard Dedekind 1831–1981; eine Würdigung zu seinem 150.
