Title: Higher linking of Knots: Stallings theorem
Speaker: Ms. Geetanjali Kachari, IISc
Date: 11 June 2007
Time: 4.00 p.m.
Venue: Lecture Hall - I, Dept. of Mathematics

A central result used in studying higher linking of knots is a theorem of Stalling on lower central series. Stallings’s proof was based on spectral sequences, but he indicated that the result can be proved directly using Hopf’s description of homology of groups. In this talk Stallings theorem will be explained and a direct proof will be presented.
