Item Coefficient bounds for certain Bazilevic maps(Romanian Academy, Romania, 2017) Sidiq, M; Babalola, Kunle OladejiFollowing Babalola [3] we obtain the best possible upper bound for the coefficients of functions in the class B_n^λ (γ) using a technique due to Nehari and Netanyahu [9] and an application of certain integral iteration of Caratheodory-type functions. The sharp bound on the Fekete-Szego functional in B_n^λ (γ) is also obtainedItem Order of schlichtness of certain linear sums(Department of Mathematics, National Tsing Hua University, Hsinchu, Taiwan, 2015) Babalola, Kunle Oladeji; Sidiq, M; Saliu, A; Ejieji, C. NIn this paper we find the largest real number ρ such that the real aprt of certain geometric quantity greater than ρ imples schlichtness of certain linear sumsItem Two radii for certain Bazilevic maps(Department of Mathematics, Faculty of Science, University of Oradea, Romania, 2018) Sidiq, M; Babalola, Kunle OladejiThe goal of this paper is the determination of the radii of two disks: (i) in which the solution of certain integral equation involving a function f∈B_n^λ (β) is in B_n^λ (β) and (ii) for which each function f∈B_n^λ (β) is σ-n-spiral univalent
