Abstract
The edge states of Abelian and non-Abelian Hall Fluids have been studi ed in a unified way from topological aspects. It is shown that the edg e current is related to the fact that the effective Berry phase of qua siparticles at the edge should be vanishing which leads to the anomaly cancellation.
