In the mathematical field of complex analysis, a branch point of a multi-valued function (usually referred to as a "multifunction" in the context of complex analysis ) is a point such that if the function is n-valued (has n values) at that point, all of its neighborhoods contain a point that has more than n values . Multi-valued functions are rigorously studied using Riemann surfaces, and the formal definition of branch points employs this concept.
