By means of(p, q)− Lucas polynomials, a class of Bazilevič functions of order ϑ + iδ in the open unit disk U of analytic and bi-univalent functions is introduced. Further, we estimate coefficients bounds and Fekete-Szegö inequalities for functions belonging to this class. Several corollaries and consequences of the main results are also obtained. © 2021 the Author(s), licensee AIMS Press.
