Abstract :In this paper we determine the radii of p-valence of the function Finsert ignore into journalissuearticles values(z); defined by F insert ignore into journalissuearticles values(z); = insert ignore into journalissuearticles values(1-X);finsert ignore into journalissuearticles values(z); H------ ^ - z f `insert ignore into journalissuearticles values( z ); , z e D where D = jz: |z | < 1J, X > 0 and the function f insert ignore into journalissuearticles values(z); belongs to certain subclasses of analytic p-valent functions with negative coefficients.
