Radius of convergence of a divergent series

A power series with a positive radius of convergence can be made into a holomorphic function by taking its argument to be a complex variable. The radius of convergence can be characterized by the following theorem: The radius of convergence of a power series f centered on a point a is equal to the distance from a to the nearest point where f cannot be defined in a way tha… WebFor multiple sums, convergence tests are performed for each independent variable.
