OverviewMulti-valued functionsDefinitionNotationOther termsSpecifying a functionRepresenting a functionGeneral properties

Several methods for specifying functions of real or complex variables start from a local definition of the function at a point or on a neighbourhood of a point, and then extend by continuity the function to a much larger domain. Frequently, for a starting point there are several possible starting values for the function. For example, in defining the square root as the inverse function of the square f
