Title: One-relator Product of Cyclic Groups

Abstract: Howie proved (2002) that any one-relator product of 3 cyclic groups is never a trivial group, via constructing a non-trivial representation to SO(3). After stating the conjecture, we first focus on S^1-equivariant homotopy. Then, we describe a sketch of the proof. We may talk about some applications or generalizations if time allows.
