Abstract:

It is known that if we apply Newton's method to the complex function F(z)=P(z)eQ(z), with deg(Q)>2, then the immediate basin of attraction of the roots of P has finite area. In this paper we show that under certain conditions on P, if deg(Q)=1, then there is at least one immediate basin of attraction having infinite area. This is a joint work with Figen Cilingir.
