A POWER series of the form?an(z - z0)n which converges at more than one point, converges inside a circle centre z0 and coincides with the series obtained by applying Taylor's theorem to the ...

Julia sets are defined by iterating a function (of a complex variable). Pick a point in the complex plane (i.e., a complex number; these can be represented as a point z=(x,y) in the plane). Now ...
