ABSTRACT

A normalized function f analytic in the open unit disc around the origin and non vanishing outside the origin can be expressed in the form z/g(z) where g(z) has Taylor coefficients bnís. Coefficient conditions in terms of bnís are derived for functions in the classes ST(K), and SP(λ,ρ) of  univalent analytic functions.
