ON A SUBCLASS OF CERTAIN STARLIKE FUNCTIONS WITH NEGATIVE COEFFICIENTS
A certain subclass <TEX>$T_{\Omega}(n,\;p,\;\lambda,\;\alpha)$</TEX> of starlike functions in the unit disk is introduced. The object of the present paper is to derive several interesting properties of functions belonging to the class <TEX>$T_{\Omega}(n,\;p,\;\lambda,\;\alpha)$</TEX>. Coefficient inequalities, distortion theorems and closure theorems of functions belonging to the class <TEX>$T_{\Omega}(n,\;p,\;\lambda,\;\alpha)$</TEX> are determined. Also we …
