Theoretical examination is made of single bunch collective effects in the collider ring of a 2 Tev 2 Tev Mu-Mu Col-lider complex. The situation involves an intense bunch, a short bunch, a small momentum compaction, a rather large impedance for the rf system, and luminosity life time lim-ited by muon decay to of the order a thousand turns. The use in rings of techniques such as BNS damping, developed for linear colliders, is discussed. Qualitative descriptions and numerical simulation results are presented.
