摘要:A function analytic in the open unit disk is said to be bi-univalent in if both the function
and its inverse map are univalent there. The bi-univalency condition imposed
on the functions analytic in makes the behavior of their
coefficients unpredictable. Not much is known about the behavior of the
higher order coefficients of classes of bi-univalent functions. We use Faber
polynomial expansions of bi-univalent functions to obtain estimates for
their general coefficients subject to certain gap series as well as
providing bounds for early coefficients of such functions.
