الملخص الإنجليزي

The dynamics of the family of meromorphic maps fλ(z) =λ tan(z) has been studied by Devaney and keen[15], while Kapoor and Prasad [21] described the dynamical behavior of the entire transcendental non-critically finite function fλ(z) = λ(ez-1) / z ; λ > 0.

In addition, Devaney [13] described some of the bifurcations that occur in the family of entire maps fλ(z) = λ exp(z) ,when λ=1.

In the present thesis the dynamics of the one parameter family Ƭ = {fλ(z) = λ sec(z) for z  , λ  R} is studied.

It is found that there exist three parameter values λi = Φ(xi) ,(i = 1,2,3), where Φ(x) = and x1, x3 are the real roots of Φ′ (x) = 0 while x2 is the solution of x + cot x = 0.

The nature of the fixed points of the family Ƭ1 = {fλ(x) = λsec(x),x R, λ R} is discussed.

The bifurcation points of the family are found.

Finally the Julia set of the function fλ(z) are investigated analytically as well as numerically.
