  1. On Some Properties of Horadam Polynomials 2009
    OpenAlex 66.2%

    In this study, we introduce a new generalization of the second order polynomial sequences. Namely, we define the Horadam polynomials se-quence. Afterwards, we investigate the some properties of the Horadam polynomials.

  2. On the solutions of two special types of Riccati difference equation via Fibonacci numbers 2013

    Abstract In this study, we investigate the solutions of two special types of the Riccati difference equation x n + 1 = 1 1 + x n and y n + 1 = 1 − 1 + y n such that their solutions are associated with Fibonacci numbers. MSC: 11B39, 39A10, 39A13.

  6. On the norms of an r circulant matrix with the generalized k Horadam numbers 2013
    YÖKSİS OpenAlex 84.3%

    In this paper, we present new upper and lower bounds for the spectral norm of an r-circulant matrix whose entries are the generalized k-Horadam numbers. Furthermore, we obtain new formulas to calculate the eigenvalues and determinant of the matrix H. MSC:11B39, 15A60, 15A15.

  7. On Randic Energy of Graphs 2014
    OpenAlex top 1% OpenAlex 99.5%

    Let G =( V, E )b e as i mple graph with vertex set V (G )= {v1 ,v 2 ,..., vn} and edge set E(G). The Randic matrix R =( rij) of a graph G whose vertex vi has degree di is defined by rij =1 / � didj if the vertices vi and vj are adjacent and rij = 0 otherwise. The Randice nergyRE is the sum of absolute values of the ei…

  10. The Energy and Sombor Index of Graphs 2022
    YÖKSİS SJR Q1 JCR Q2 OpenAlex top 1% OpenAlex 99.2%

    The energy of a graph is defined to be the sum of absolute values of eigenvalues of its adjacency matrix. The Sombor index of a graph is a novel topological indexof a graph. In this paper, we study relations between energy and Sombor index of a graph in terms of its degrees. Moreover, we give upper bound for a regular…

    OpenAlex top 10% OpenAlex 96.2%

    The main purposes of this paper are to introduce and investigate the Harary energy and Harary Estrada index of a graph. In addition we establish upper and lower bounds for these new energy and index separately.
