Sylow's theorems

Further information: Sylow's theorem While a substitute lecturer at Christiana University, Sylow posed some questions that led to the notion of Sylow subgroup. In 1872, he published a paper describing the Sylow's theorems, which state that for any finite group G:

  • There exist p-Sylow subgroups for any p dividing the order of G
  • The p-Sylow subgroups are all conjugate and the number of such subgroups is 1 modulo p
  • Any p-subgroup is contained in a p-Sylow subgroup

Editing work

Along with Sophus Lie, Sylow worked on editing the papers of of Abel.
