Abstract
In this work, we consider certain class of bi-univalent functions related with shell-like curves related to \(\kappa \)-Fibonacci numbers. Further, we obtain the estimates of initial Taylor–Maclaurin coefficients (second and third coefficients) and Fekete–Szegö inequalities. Also we discuss the special cases of the obtained results.
