Coefficient estimates for starlike and convex functions related to sigmoid functions

UDC 517.5 We give sharp coefficient bounds for starlike and convex functions related&nbsp;to modified sigmoid functions.&nbsp;We also provide some sharp coefficients bounds for the inverse&nbsp;&nbsp;functions and sharp bounds for the initial logarithmic coeffic...
