Sb. Joshi et al., CERTAIN CLASSES OF MEROMORPHIC FUNCTIONS WITH POSITIVE AND MISSING COEFFICIENTS, Journal of mathematical analysis and applications, 193(1), 1995, pp. 1-14
The main object of the present paper is to introduce certain novel sub
classes of meromorphic functions with positive and missing coefficient
s and investigate their basic properties including, for example, coeff
icient estimates, distortion theorem, and the radii of starlikeness an
d convexity. It is also proved that one of the classes (considered her
e) is closed under convex linear combinations. The various results obt
ained in this paper are shown to be sharp. (C) 1995 Academic Press, In
