英文摘要 | The main object of this paper is to study the class of analytic functions with negative coefficients and with fixed second coefficient. Among other results of interest, we derive coefficient estimates, closure properties involving convex linear combinations) growth and distortion theorems, and radii of starlikeness and convexity for functions in tlie class. Many of these results are further extended to hold true for families of functions with finitely many fixed coefficients. |
