We have also discussed about some amazing features shown by the periodic numbers and rotation numbers related to the primary bulbs of the Mandelbrot set. KEYWORDS: Critical Point, Julia Set, Mandelbrot Set, Fixed Point, Periodic Point, Primary Bulb, Iteration of a Map, Rotation Number, Schwarzian Derivative 1. INTRODUCTION The Mandelbrot set has a celebrated place in fractal geometry, a field first investigated by the French Mathematicians, Gaston Julia and Pierre Fatou, as a part of complex dynamics in the beginning of the 20th century. Gaston Julia (1893-1978) wrote a paper titled, "M´emoire sur l’iteration des fonctions rationelles" (A Note on the Iteration of Rational Functions) [19], where, he first introduced the modern idea of a Julia set as a part of complex dynamics. In this paper, Julia gave a precise description of the set of those points of the complex plane, whose orbits under the iteration of a rational function stayed bounded.
