A correct proof of logarithmic coefficients for Janowski type $(j,k)$-symmetric starlike functions

Abstract

Recently, authors [7] studied the logarithmic coefficient bounds for class of the Janowski type $(j,k)$-symmetric starlike functions ${\mathcal{S}\mathcal{T}}_{[j,k]}(A,B)$ in ({\em Rev. Real Acad. Cienc. Exactas Fis. Nat. Ser. A-Mat.} (2022). DOI: 10.1007/s13398-022-01310-9). We pointed out that the proof of Theorem~3 in [7] is incorrect. In this article, we present the correct proof of Theorem~3. In addition, we also obtain some new results related to the logarithmic coefficient inequalities for the class ${\mathcal{S}\mathcal{T}}_{[j,k]}(A,B)$.
