  On the limit of the Goodwillie tower of the identity

  The Goodwillie tower of the identity on a space X is a tower of spaces under X that approximates its homotopy type through increasingly nonlinear information. For instance, the first stage captures the stable homotopy of X, while the second also detects its metastable homotopy. When X is simply connected (or, more generally, nilpotent), the tower 'converges': its limit recovers the homotopy type of X. For general spaces, however, the limit behaves rather mysteriously. In this talk, I will discuss work in progress with Connor Malin in which we describe the limit of this tower in more familiar terms, and use this description to deduce convergence for a large class of spaces.
