Abstract

In the standard theory of Mackey functors for a group $G$, the group is either finite, or a compact Lie group. In the present paper, we develop an alternative notion of a Mackey profunctor that works better for profinite groups. The most important practical example is $G=\widehat {\mathbb {Z}}$, the profinite completion of the group of the integers, and in this case, our Mackey profunctors appear naturally in the theory of cyclotomic traces.
