A Method for Decision Making Problems by Using Graph Representation of Soft Set Relations
(Tsi Press, 2019)
Soft set theory, which was defined by D. Molodtsov, has a rich potential for applications in several fields of life. One of the successful application of the soft set theory is to construct new methods for Decision Making ...
New Wave Simulations to the (3+1)-Dimensional Modified Kdv-Zakharov-Kuznetsov Equation
(Amer Inst Physics, 2017)
In this study, we apply an effective method which is improved Bernoulli sub-equation function method (IBSEFM) to the (3+1)-dimensional modified KdV-Zakharov-Kuznetsov equation. It gives some new wave simulations such as ...
Geodetic convex boundary curvatures of the communities in stock market networks
(Elsevier Science Bv, 2018)
We analyze the daily returns of stock market indices of NASDAQ and S&P 500 over the period of 2004-2015. We build network models by using a threshold method that captures strong relations amongst the agents. We also subdivide ...
A numerical approach for solving generalized Abel-type nonlinear differential equations
(Elsevier Science Inc, 2015)
In this paper, a numerical power series algorithm which is based on the improved Taylor matrix method is introduced for the approximate solution of Abel-type differential equations and also, Riccati differential equations. ...
A threshold method for financial networks and geometric scattering of agents
(Taylor and Francis Ltd., 2019)
Various filtering methods are applied to financial networks to overcome dimensionality problem of financial networks. In this study, we present a new threshold method based on Triangular Maximally Filtered Graph (TMFG) ...
Soft sets and soft rings
(Pergamon-Elsevier Science Ltd, 2010)
Molodtsov (1999) introduced the concept of soft sets in [1]. Then, Maji et al. (2003) defined some operations on soft sets in [2]. Aktas and Cagman (2007) defined the notion of soft groups in [3]. Finally, soft semirings ...
Topological structure of fuzzy soft sets
(Pergamon-Elsevier Science Ltd, 2011)
In this paper, the concept of fuzzy soft topology is introduced and some of its structural properties such as neighborhood of a fuzzy soft set, interior fuzzy soft set, fuzzy soft basis, fuzzy soft subspace topology are ...
A collocation method using Hermite polynomials for approximate solution of pantograph equations
(Pergamon-Elsevier Science Ltd, 2011)
In this paper, a numerical method based on polynomial approximation, using Hermite polynomial basis, to obtain the approximate solution of generalized pantograph equations with variable coefficients is presented. The ...
A Chebyshev Polynomial Approach for High-Order Linear Fredholm-Volterra Integro-Differential Equations
