On λ-pseudo bi-starlike functions related with Fibonacci numbers. Communications in Mathematics, 32(1), 117-127.1804-1388https://cm.episciences.org/10870https://hdl.handle.net/11468/13449In this paper we define a new subclass λ-bi-pseudo-starlike functions of Σ related to shell-like curves connected with Fibonacci numbers and determine the initial Taylor-Maclaurin coefficients |a2| and |a3| for f. Further we determine the Fekete-Szegö result for the function class and for special cases, corollaries are stated which some of them are new and have not been studied so far.eninfo:eu-repo/semantics/openAccessAnalytic functionsbi-univalentFibonacci numbersShell-like curveStarlike functionsArticle3211171272-s2.0-8517206913310.46298/cm.10870Q3
