Journal of Computational and Applied Mathematics on the Semilocal Convergence of Efficient Chebyshev–secant-type Methods

We introduce a three-step Chebyshev-Secant-type method (CSTM) with high efficiency index for solving nonlinear equations in a Banach space setting. We provide a semilocal convergence analysis for (CSTM) using recurrence relations. Numerical examples validating our theoretical results are also provided in this study.
