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 to modified sigmoid functions. We also provide some sharp coefficients bounds for the inverse  functions and sharp bounds for the initial logarithmic coeffic...
