Furthermore, we establish bounds for the coefficients for these subclasses and several related classes are also considered and connections to earlier known results are made.eninfo:eu-repo/semantics/openAccessScience & technologyPhysical sciencesMathematicsArticle000215639900004201510.1155/2015/2416832314-4785
