Acu, Mugur; Eker, Sevtap Sumer An integral operator on analytic functions with negative coefficients. (English) Zbl 1199.30038 Acta Univ. Apulensis, Math. Inform. 18, 179-183 (2009). Summary: We consider an integral operator on analytic functions and prove some preserving theorems regarding some subclasses of analytic functions with negative coefficients.
