摘要
In the present paper, the author introduce two new subclasses S-sc((k)) (alpha, beta, gamma) of close-to-convex functions and C-sc((k)) (alpha, beta, gamma) of quasi-convex functions with respect to 2k-symmetric conjugate points. The coefficient inequalities and integral representations for functions belonging to these classes are provided, the inclusion relationships and convolution conditions for these classes are also provided.
