Applications of (M,N)-Lucas polynomials for holomorphic and bi-univalent functions
Wanas Abbas Kareem (Department of Mathematics, College of Science, University of Al-Qadisiyah, Iraq), abbas.kare.w@qu.edu.iq
In this article, we use the (M,N)-Lucas polynomials to define a new
family HΣ(λ,x) of normalized holomorphic and bi-univalent functions and to
establish the bounds for |a2| and |a3|, where a2, a3 are the initial
Taylor-Maclaurin coefficients. Further we investigate Fekete-Szegö inequality
for functions in the family HΣ(λ,x) which we have introduced here.
