  • A New Efficient High Order Four-Step Multiderivative Method for the Numerical Solution of Second-Order IVPs with Oscillating Solutions 

    Shokri, Ali؛ Mehdizadeh Khalsaraei, Mohammad (University of Kashan, 2020-06-01)
    In this paper, we present a new high order explicit four-step method of eighth algebraic order for solving second-order linear periodic and oscillatory initial value problems of ordinary differential equations such as ...

  • Tension Reduction between Planck data and LSS by Dynamical Dark Energy Model 

    Ebrahimi, Aghile؛ Monemzadeh, Majid؛ Moshafi, Hossein؛ Movahed, Seyed Mohammad Sadegh (University of Kashan, 2020-06-01)
    In this paper, we consider the dynamical dark energy model (Feng model) to reveal the discrepancy between CMB and LSS data raised by ΛCDM model. In order to constrained free parameters, we utilize two combined sets namely ...

  • Toplogical and Geometric KM-Single Valued Neutrosophic Metric Spaces 

    Hamidi, Mohammad؛ MOLLAEI ARANI, MEHDI؛ ALIPOUR FAKHRI, YOUSEF ALIPOUR FAKHRI (University of Kashan, 2020-06-01)
    ‎This paper introduces the novel concept of KM-single valued neutrosophic metric spaces as an especial generalization of KM-fuzzy metric spaces‎, ‎investigates several topological and structural properties and presents ...

  • The Zagreb Index of Bucket Recursive Trees 

    Kazemi, Ramin؛ Behtoei, Ali؛ Kohansal, Akram (University of Kashan, 2020-06-01)
    ‎Bucket recursive trees are an interesting and natural generalization of recursive trees‎. ‎In this model the nodes are buckets that can hold up to b>= 1 labels‎. ‎The (modified) Zagreb index of a graph is defined as the ...

  • Numerical Calculation of Fractional Derivatives for the Sinc Functions via Legendre Polynomials 

    Saadatmandi, Abbas؛ Khani, Ali؛ Azizi, Mohammad-Reza (University of Kashan, 2020-06-01)
    ‎This paper provides the fractional derivatives of‎ ‎the Caputo type for the sinc functions‎. ‎It allows to use efficient‎ ‎numerical method for solving fractional differential equations‎. ‎At‎ ‎first‎, ‎some properties ...

  • On L(d,1)-labelling of Trees 

    Hrastnik, Irena؛ Žerovnik, Janez (University of Kashan, 2020-06-01)
    Given a graph G and a positive integer d, an L(d,1)-labelling of G is a function f that assigns to each vertex of G a non-negative integer such that if two vertices u and v are adjacent, then |f(u)-f(v)|>= d and if u and ...
