Bi-univalent functions constitute a significant subclass of analytic functions defined on the open unit disc, characterised by the property that both the function and its inverse are univalent. This ...
Estimating the conditional quantiles of outcome variables of interest is frequent in many research areas, and quantile regression is foremost among the utilized methods. The coefficients of a quantile ...
The Hayman $T_a$ function for the asymptotic distribution of the coefficients of univalent functions has a continuous derivative which is closely related to the ...
