    Bounds on coefficients of certain analytic functions
    (Faculty of Science, University of Ilorin, Ilorin, Nigeria, 2013) Jimoh, F. M.; Ganiyu, M. A.; Ejieji, C. N.; Babalola, Kunle Oladeji
    In this paper, we obtain bounds on some early coefficients of analytic functions which have the form f(z)=z+a_2 z^2+⋯ and which satisfy certain geometric conditionsin the open unit disk E={z∈ C:|z|<1}

    Coefficient estimates for certain classes of analytic functions
    (Nigerian Mathematical Society, 2014) Ganiyu, M. A.; Jimoh, F. M.; Ejieji, C. N.; Babalola, Kunle Oladeji
    Bounds on early coefficients of analytic functions normalized by f(0)=f^'(0)-1=0 which satisfy Re (〖f(z)〗^(α-1) f^' (z))/z^(α-1) (1+(zf^'' (z))/(f^' (z) ))>0 in the unit disk U ={z∈ C:|z|<1} are obtained using known properties of functions with positive real part

    Cousins of the Bernoulli Inequality
    (Faculty of Science, University of Ilorin, Ilorin, Nigeria, 2012) Babalola, Kunle Oladeji; Ejieji, C. N.
    We present elementary inequalities of Bernoulli type, which have applications in the theory of inequalities, especially the geometric function theory

    A generalization of starlikeness condition
    (Nigerian Mathematical Society, 2016) Ejieji, C. N.; Babalola, Kunle Oladeji
    In this paper, we prove a generalization of a well known starlikeness condition in the unit disk using a method of linear combinations of certain geometric expressions. Some interesting corollaries are mentioned

    Optimal Test Strategies for HBV-HIV Co-Infection Model
    (2019) Dotia, A. K.; Ibrahim, M. O.; Ejieji, C. N.; Bello, K. A.; Ahmed, B. M.; Ajanaku, B.; Kazeem, A. B.; Lawan, A. O.
    In this paper, we present a deterministic model for the co-interaction of HBV and HIV in a population. Mathematical analyses are carried out, which determines the positivity of solution and optimal control. This study examined the effectiveness of the efforts put in place in eliminating the birth of prenatally infected chronic carrier mother, considering the efficacy of prophylactic vaccine against the incidence of new cases. The scheme shows that the disease can be resisted with vaccination(s) and treatment.
