    Relationships Between Tropical Eigenvectors and Tropical Fixed Points of the Group gl(2, R)
    (Forum Editrice Univ Udinese, 2020) Hayat, Umar; Farid, Ghulam; Karapinar, Erdal; Mathematics
    The eigenvalues, eigenvectors and fixed points of matrices have many applications in various branches of science and many mathematical disciplines. In this paper first we introduce the concept of tropical fixed points, then we calculate the tropical eigenvalues and tropical eigenvectors of GL(2, R). Furthermore we give relationships between tropical eigenvectors and tropical fixed points of GL(2, R).

    EXISTENCE OF FIXED POINTS FOR NEW PRESIC TYPE MULTIVALUED OPERATORS
    (Yokohama Publ, 2017) Ali, Muhammad Usman; Kamran, Tayyab; Karapinar, Erdal
    In this paper, we shall generalize the convergence theorem introduced by Presic in 1965, by introducing the notions of alpha-Presic type contractive multivalued operators. We shall also construct some examples to prove the generality of our results.
