Abstract

We show that there is only one embedding of BDI2 in BF4 at the prime p = 3, up to self-maps of BDI2. We also describe the effect of the group of self-equivalences of BF4at the prime p = 3 on this embedding and then show that the Friedlander exceptional isogeny composed with a suitable Adams map is an involution of BF4whose homotopy fixed point set coincide with BDI2 © 2001 American Mathematical Society.
