It has been pointed out to
me by W. Lellmann and K. Knapp that there are two difficulties with the paper
bo-resolutions [M1]. First, the statement of the main theorem claims more than is
proved, and second, the proof of the vanishing line is incomplete. In this note a
corrected theorem and a discussion of where the error occurs are given. The vanishing
line is discussed in complete detail in the third part of this note. Before that
discussion occurs, we will show how the several applications of [M1] still
follow.
§1 contains a correct statement of the main theorem of [M1] and a discussion of
the error. §2 shows how the v1-periodicity theorem and the results of [DGM]
follow from the revised main theorem. §3 discusses the vanishing line for
bo-resolutions.
