On a fekete–szegö problem associated with generalized telephone numbers.

The results of this research are dedicated to determine upper coefficient estimates and the Fekete–Szegö problem in the class (Formula presented.), which is defined by generalized telephone numbers. We also indicate some specific conditions and consequences of results found by us.eninfo:eu-repo/semantics/openAccessbi-univalent functionFekete–Szegö problemHolormorphic functionTelephone numbersUpper boundsOn a fekete–szegö problem associated with generalized telephone numbersOn a fekete–szegö problem associated with generalized telephone numbersArticle111518WOS:0010464051000012-s2.0-8516759666310.3390/math11153304Q1N/A
