    (University of Mazandaran, 2024) Gülbahar, Mehmet; Kılıç, Erol; Erkan, Esra; Kavuk, Ecem
    Concircular vector fields on lightlike submanifolds are investigated. With the aid of this review, some relations on Ricci soliton lightlike submanifolds containing concircular vector fields are obtained. © 2023 by University of Mazandaran.

    Ricci Soliton Lightlike Submanifolds with Co-Dimension $2$
    (2023) Kılıc, Erol; Gulbahar, Mehmet; Erkan, Esra; Kavuk, Ecem
    The necessary requirements for half-lightlike and coisotropic lightlike submanifolds to be a Ricci soliton are obtained. Some examples of Ricci soliton half-lightlike and Ricci soliton coisotropic lightlike submanifolds are given. The Ricci soliton equation is investigated on totally geodesic, totally umbilical, and irrotational lightlike submanifolds.
