Our objective is to give a sufficiently complete description of these spaces with the emphasis on those quasi-join diagrams which resemble the diagrams associated with lens spaces. The central result is a "recognition" theorem which is intended to serve as a principal result in a homological description of more complex, shellable spaces. |
