We prove that every p -local compact group is approximated by transporter systems over finite p -groups. To do so, we use unstable Adams operations acting on a given p -local compact group and study the structure of resulting fixed points.
55R35; 20D20The theory of p -local compact groups was introduced by C Broto, R Levi and B Oliver [7] as the natural generalization of p -local finite groups, also introduced by the same authors in [5], to include some infinite structures, such as compact Lie groups or p -compact groups, in an attempt to give categorical models for a larger class of p -completed classifying spaces.Nevertheless, when passing from a finite setting to an infinite one, some of the techniques used in the former case are not available any more. As a result, some of the more important results in [5] were not extended to p -local compact groups, and, roughly speaking, p -local compact groups are not yet as well understood as p -local finite groups. It is then the aim of this paper to shed some light on the new theory introduced in [7].
