Brief introduction  

In future We have developed local as well as semi-local convergence analysis of third order iterative methods such as Chebyshev's, Chebyshev-Halley and modified Newton-like methods used to find zeros of non-linear operator equations in Banach spaces. For showing local and semi-local convergence of above mentioned methods we used new type of majorant conditions which were earlier introduced by Argyros and Ren (2012) and Ling and Xu (2014).  Moreover, two particular cases of the convergence analysis namely under Kantorovich-type, Smale-type and Nesterov-Nemirovskii condition have also presented for both local and semi-local convergence analysis.

We will study convergence of another higher order iterative methods in Banach spaces by using majorant conditions, recurrence relations under different continuity conditions on the operator. We will also study local and semi-local convergence of these methods under Riemannian manifold settings.
