Generalized Analytic Function Classes Using an Extended Two-Factor q-Differential Operator: Fekete–Szegő Problem

CAUCHY Jurnal Matematika Murni dan Aplikasi · 2026-10-13 · 期刊论文

In this paper, we introduce an extended two-factor q-differential multiplier operator denoted by ℳq,,n,mf(z). Using this operator, we define the associated subclasses Xq,,n,m() and Yq,,n,m(,) of analytic functions. We obtain upper bounds for the initial coefficients a2, a3 and FeketeSzeg inequalities for the functional |a3 a22| for functions belonging to these subclasses. The bounds are derived by reducing the coeffi…
