Abstract

By using a certain general conic domain as well as the quantum (or q -) calculus, here we define and investigate a new subclass of normalized analytic and starlike functions in the open unit disk U . In particular, we find the Hankel determinant and the Toeplitz matrices for this newly-defined class of analytic q -starlike functions. We also highlight some known consequences of our main results.
