In doing so we extend Williamson's theorem on normal forms when there is no symmetry present.Using standard representation-theoretic results the symmetry can be factored out and we reduce to finding normal forms over a real division ring. There are three real division rings consisting of the real, complex and quaternionic numbers. Of these, only the real case is covered in Williamson's original work."}],"date_updated":"2020-05-19T07:15:35Z","publication_identifier":{"issn":["0305-0041","1469-8064"]},"publication":"Mathematical Proceedings of the Cambridge Philosophical Society","author":[{"full_name":"Melbourne, Ian","last_name":"Melbourne","first_name":"Ian"},{"last_name":"Dellnitz","first_name":"Michael","full_name":"Dellnitz, Michael"}],"doi":"10.1017/s0305004100071577","language":[{"iso":"eng"}]}]
