Example 4.10.  Show that the Julia set for  [Graphics:Images/JuliaMandelbrotMod_gr_144.gif]  is connected.

Solution.  We apply Theorem 4.9 and compute the orbits of 0 for  [Graphics:Images/JuliaMandelbrotMod_gr_145.gif].  We have  [Graphics:Images/JuliaMandelbrotMod_gr_146.gif],  [Graphics:Images/JuliaMandelbrotMod_gr_147.gif],  [Graphics:Images/JuliaMandelbrotMod_gr_148.gif],  and  [Graphics:Images/JuliaMandelbrotMod_gr_149.gif].  Thus the orbits of 0  are the sequence  [Graphics:Images/JuliaMandelbrotMod_gr_150.gif],  which is clearly a bounded sequence.  Thus, by Theorem 4.9, the Julia set for  [Graphics:Images/JuliaMandelbrotMod_gr_151.gif]  is connected.

We apply Theorem 4.8 and compute the orbits of  0  for  [Graphics:../Images/JuliaMandelbrotMod_gr_152.gif].  

[Graphics:../Images/JuliaMandelbrotMod_gr_153.gif]




[Graphics:../Images/JuliaMandelbrotMod_gr_154.gif]

 

Thus, the orbits of  0  is the sequence  [Graphics:../Images/JuliaMandelbrotMod_gr_155.gif]  which is clearly a bounded sequence.  Thus, by Theorem 4.14, the Julia set for  [Graphics:../Images/JuliaMandelbrotMod_gr_156.gif]  is connected.
