Abstract

We show that a Fell bundle B = {B_t}_{t in F}, over an arbitrary free group F, is amenable, whenever it is orthogonal (in the sense that B_x^*B_y = 0, if x and y are distinct generators of F) and ß(in the sense that B_ts coincides with the closed linear span of B_tB_s, when the multiplication “ts” involves no cancelation).
