摘要：
In this paper, we investigate subclasses of univalent functions over | z| < 1, using the characterization of starlikeness and Noor integral operator defined by convolution of analytic functions. We also give coefficient bounds for the class of a-spiral function of order. and k-uniformly a-spirallike functions. Moreover, we provide some examples of univalent functions to illustrate our results. Keywords: q-analogue, bi-univalent functions, non-integer order,
