Univalent functions associated with the symmetric points and cardioid-shaped domain involving (p, q)-calculus. Kyungpook Mathematical Journal, 61(1), 75-98.1225-6951https://doi.org/10.5666/KMJ.2021.61.1.75https://hdl.handle.net/11413/8212In this paper, we introduce new classes of post-quantum or (p, q)-starlike and convex functions with respect to symmetric points associated with a cardiod-shaped domain. We obtain (p,q)-Fekete-Szego inequalities for functions in these classes. We also obtain estimates of initial (p, q)-logarithmic coefficients. In addition, we get q-Bieberbachde-Branges type inequalities for the special case of our classes when p = 1. Moreover, we also discuss some special cases of the obtained results.eninfo:eu-repo/semantics/restrictedAccess(p. q)-Fekete-Szego inequalitiesArticle0006294408000072-s2.0-85103325421
