In this paper, we introduce and investigate a new class of bi- univalent functions defined in the open unit disk involving a general integral operator associated with the general Hurwitz- Lerch Zeta function denoted by
. The main result of the investigation is to estimate the upper bounds for the initial Taylor–Maclaurin coefficients of functions
and
for this class. Following, we find the second Hankel determinant. Several new results are shown after specializing the parameters employed in our main results.
Keywords: Hankel determinant, Bi-univalent functions, coefficient bounds, Hurwitz -Lerch zeta function.
