    Skew ABC energy of digraphs
    (Ankara Üniversitesi, 2022) Yalçın, N. Feyza; Büyükköse, Şerife; Other; Other
    In this paper, skew ABC matrix and its energy are introduced for digraphs. Firstly, some fundamental spectral features of the skew ABC matrix of digraphs are established. Then some upper and lower bounds are presented for the skew ABC energy of digraphs. Further extremal digraphs are determined attaining these bounds.
