Moreover, we use the Faber polynomial expansions and Fibonacci numbers to derive bounds for the general coefficient vertical bar a(n)vertical bar of the bi-univalent function class.eninfo:eu-repo/semantics/openAccessCoefficientBi-univalent functionsSubordinationFaber polynomialsFibonacci numbersKomatu integral operatorScience & technologyPhysical sciencesMathematicsA subclass of bi-univalent functions based on the faber polynomial expansions and the fibonacci numbersArticle0004608025000507210.3390/math70201602227-7390
