  • Vertex weighted Laplacian graph energy and other topological indices 

    Sharafdini, Reza؛ Panahbar, Habibeh (Shahid Rajaee Teacher Training University, 2016-06-01)
    Let $G$ be a graph with a vertex weight $omega$ and the vertices $v_1,ldots,v_n$. The Laplacian matrix of $G$ with respect to $omega$ is defined as $L_omega(G)=diag(omega(v_1),cdots,omega(v_n))-A(G)$, where $A(G)$ is the ...

  • Computing Degree-Based Topological Indices of Polyhex Nanotubes 

    Shigehalli, Vijayalaxmi؛ Kanabur, Rachanna (Shahid Rajaee Teacher Training University, 2016-06-01)
    Recently, Shigehalli and Kanabur [20] have put forward for new degree based topological indices, namely Arithmetic-Geometric index (AG1 index), SK index, SK1 index and SK2 index of a molecular graph ...

  • New version of degree-based topological indices of certain nanotube 

    Shigehalli, Vijayalaxmi؛ Kanabur, Rachanna (Shahid Rajaee Teacher Training University, 2016-06-01)
    In this paper, computation of the Arithmetic-Geometric index (AG1 index), SK index, SK1 index and SK2 index of H-Naphtalenic nanotube and TUC4[m,n] nanotube. We also compute SK3 ...

  • A study on Landau levels in thin films 

    Ahmadi, Fatemeh؛ Saadat, Mehdi؛ Bahrampori, Zainab (Shahid Rajaee Teacher Training University, 2016-06-01)
    In this paper, we study the energy levels of an electron moving in a thin film. This film is considered as a two-dimensional electron gas which is under the influence of a uniform external magnetic field B and a uniform ...

  • On the energy of fullerene graphs 

    Songhori, Mahin؛ Ghorbani, Modjtaba (Shahid Rajaee Teacher Training University, 2016-06-01)
    The concept of energy of graph is defined as the sum of the absolute values of the eigenvalues of a graph. Let λ1, λ2, . . . , λn be eigenvalues of graph G, then the energy of G is defined ...
