"An Introduction to Orbifolds"

It is well-known that the orbit space of a group action on a manifold is generally not a manifold. However, such quotients appear frequently in physics and geometry and possess certain characteristics that make them interesting objects to study. In this talk, we introduce a subclass of these spaces, called orbifolds, and consider different examples coming from both geometry and physics.
