Topological methods in group theory 论文

摘要

This article is a revised version of notes on an advanced course given in Liverpool from January to March 1977 in preparation for the symposium. The lectures given by Terry Wall at the symposium were mainly taken from Sections 3 and 4, and much of the material in John Stallings' lectures is in Sections 5 and 6. It seemed worth publishing the whole, as a rather full introduction to the area for those with a background in topology. Originality is not claimed for the results in the earlier sections (though full references have not always been given), but the uniqueness results in Section 7 and most of Section 8 are due to Peter Scott.
