TOPIC: On the isoperimetric functions of one-relator groups
 
DATE: POSTPONED TILL MAY 30.
  
Abstract : It has been conjectured by several researchers that
the possible isoperimetric functions of one relator groups are:
linear, quadratic, exponential and the third Ackermann function.
In a work in progress I plan to check this conjecture, using a generalized
version of small cancellation theory. The problem
is divided into 6 subproblems, the first of which already has
been resolved. In the talk I will present this result.
