چکیده
We study the connection between the Goodwillie tower of the identity and the lower central series of the loop group on connected spaces. We define the simplicial theory of homotopy n-nilpotent groups. This notion interpolates between infinite loop spaces and loop spaces. We prove, that the set-valued algebraic theory obtained by applying π0 is the theory of ordinary n-nilpotent groups and that the Goodwillie tower of a connected space is determined by a certain homotopy left Kan extension. Finally we prove, that n-excisive functors of the form ΩF have values in homotopy n-nilpotent groups.

The Dwyer-Wilkerson space DI(4) is the only exotic 2-compact group. We compute its v1-periodic homotopy groups v 1 π∗(DI(4)).

We generalize the methods of Moy-Prasad, in order to define and study the genuine depth zero representations of some nonlinear covers of reductive groups over p-adic local fields. In particular, we construct all depth zero supercuspidal representations of the metaplectic group Mp2n over a p-adic field of odd residue characteristic.

In this paper, we study Z2 actions on a 3-cell complex X having its cohomology ring isomorphic to that of the wedge sum P (n) ∨ S or S ∨ S ∨ S . We determine the possible fixed point sets depending on whether or not X is totally non-homologous to zero in XZ2 and give examples of all possible cases.
