“…Using the concept of subordination, several subclasses of analytic functions were defined by condition (1.3) on the basis of geometrical interpretation of the image domain p(U). Some interesting geometrical structures are like right half plane [7], circular disk [9], conic domain [1,10,11,13], cardioid domain [14,22], generalized conic domains [16], oval and petal type domains [17], leaf-like domain [2,3,21,26], Bernoulli lemniscate [12,24] and the most concerning one is the shelllike curve [4-6, 8, 19, 20, 23, 25]. A general approach to the classes of functions defined by subordination (1.3) can be found in [15].…”
