Man-Chuen Cheng, Man-Chun Lee, Luen-Fai Tam

Motivated by the work of Li and Mantoulidis, we study singular metrics which are uniformly Euclidean $(L^{\infty})$ on a compact manifold $M^{n}$ ( $n \geq 3$ ) with negative Yamabe invari…

Alejandro Adem, Man Chuen Cheng

We provide descriptions for the moduli spaces $Rep (Γ, P U (m))$ , where $Γ$ is any finitely generated abelian group and $P U (m)$ is the group of $m \times m$ projective unitary m…
