Abstract :
In this article, the authors introduce two new subclasses of a class m-fold symmetric biunivalent functions in open unit disk. Coefficient bounds for the Taylor-Maclaurin coefficients |am+1| and |a2m+1| are are obtain . Furthermore, we solve Fekete-Szego¨ functional problems for functions in F∑ ,m(γ, µ, ϑ) m∑,m(κ, η, ϑ) . Also, several certain special improver results for the associated classes are presented .
