THE 4TH INNOVATION AND ANALYTICS CONFERENCE & EXHIBITION (IACE 2019).
Denote S*(α, β, δ) as the subclass of analytic functions f defined by f(z)=z+∑n=2∞anzn that satisfied Reeiδ{ zf′(z)+αz2f″(z)f(z) }>β in open unit disk, z∈D={z:|z| 0. In this paper, we obtain sharp upper bound for the second Hankel det

Letfbe analytic in the unit diskD={z∈C: |z| < 1}, andSbe the subclass of normalized univalent functions inD. We define the class of tilted bi-starlike functionsSσ*(β,δ), which satisfy the conditionRe{eiδ[zf'(z)f(z)]}>βwhere |δ| <πand cosδ>
