A branched covering is a concept in topology, specifically in the study of covering spaces. It refers to a specific type of continuous surjective map between two topological spaces, typically between manifolds or Riemann surfaces, which behaves like a covering map except for certain points, called branch points, where the behavior is more complicated.
