Hacettepe Journal of Mathematics and Statistics, 51(1), 156-171.https://doi.org/10.15672/hujms.778148https://hdl.handle.net/11413/7892In this paper, we consider two Ma-Minda-type subclasses of starlike and convex functions associated with the normalized analytic function phi(Ne)(z) = 1 + z - z3/3 that maps an open unit disk onto the Nephroid shaped bounded domain in the right-half of the complex plane. We investigate convolution and quasi-Hadamard product properties for the functions belonging to such classes. In addition, we compute best possible estimates on third order Hermitian-To eplitz determinant and non-sharp estimates on certain third order Hankel determinants for the starlike functions associated with the interior region of Nephroid.eninfo:eu-repo/semantics/openAccessStarlike FunctionsConvex FunctionsNeproidConvolution PropertiesQuasi-hadamard Product PropertiesHermitian--toeplitz and Hankel DeterminantsArticle0007603846000122651-477X
