Abstract
Recently, there have been many works related with dynamics of various functions. In this paper, singular
values and fixed points of generating function of Genocchi numbers, \(g_\lambda(z) = \lambda \frac{2z}
{e^z+1}, (\lambda\in R) > 1\), are
investigated. It is shown that the function \(g_\lambda(z)\) has infinitely many singular values and its critical values
lie in the left half plane and one point on the real axis in the right half plane. Further, the real fixed
points of \(g_\lambda(z)\) and their nature are determined. Finally, we provide numerical evidence of the existence of
chaotic phenomena by illustrating bifurcation diagrams of system and by calculating the Lyapunov exponent.
