Subsequently, in 1967, Brannan and Clunie [2] introduced bistarlike functions and biconvex functions similar to the familiar subclasses of univalent functions consisting of strongly starlike, strongly convex, starlike, and convex functions and so on and obtained estimates on the initial coefficients conjectured that [absolute value of ([a.sub.2])] [less than or equal to] [square root of 2] for bistarlike functions and [absolute value of ([a.sub.2])] [less than or equal to] 1 for biconvex functions.
