Abstract

In this article, we represent and examine a new subclass of holomorphic and bi-univalent functions defined in the open unit disk $\mathfrak{U}$, which is associated with the Dziok-Srivastava operator. Additionally, we get upper bound estimates on the Taylor-Maclaurin coefficients $|a_{2}|$ and $|a_{3}|$ of functions in the new class and improve some recent studies.
