Abstract .
In this paper, we define an index of the convexity measure by
means of the logarithmic operator . As an application , we study the
influence of the convexity on Newton method for solving nonlinear
equations. Then we define a family of Newton type iterative processes t o
solve a complex or scalar nonlinear equation, we can always apply an
iterative process of this family faster than Newton method .

1. Introduction .
We begin this paper defining an index of the convexity measure for a
function h at each point . We prove that it is a good measure of the
