Qualitative Behavior of a Quadratic Second-Order Rational Difference Equation -by M. B. Almatrafi, E. M. Elsayed and Faris Alzahrani

Abstract: This article demonstrates the existence of boundedness, asymptotic behavior and the periodicity of the following quadratic second-order rational difference equation: \begin{equation*} x_{n+1}=ax_{n}+\dfrac{bx_{n}^{2}+cx_{n}x_{n-1}+dx_{n-1}^{2}}{\alpha x_{n}^{2}+\beta x_{n}x_{n-1}+\gamma x_{n-1}^{2}},\;\;\;n=0,1,..., \end{equation*} where the constants $a,\ b,\ c,\ d,\ \alpha ,\ \beta $ and $\gamma $ are positive real numbers and...

Method for solving Lane-Emden type differential equations by Coupling of wavelets and Laplace transform -by Jai Prakesh Jaiswal and Kailash Yadav

Method for solving Lane-Emden type differential equations by Coupling of wavelets and Laplace transform -by Jai Prakesh Jaiswal and Kailash Yadav

Abstract: The objective of this paper is to obtain the numerical solution of Lane-Emden type equations by coupling method of Laplace transform and Chebyshev wavelets. By using the properties of Laplace transform and Chebyshev wavelets, an operational matrix is derived to convert the Lane-Emden equations into...

Dual Skew Semi-Heyting Almost Distributive Lattices -by Berhanu Assaye, Mihret Alamneh and Yeshiwas Mebrat

Dual Skew Semi-Heyting Almost Distributive Lattices -by Berhanu Assaye, Mihret Alamneh and Yeshiwas Mebrat

Abstract: In this paper we introduce the concept of dual skew SHADLs and characterize it in terms of dual SHADL. We define an equivalence relation $\theta$ on a dual skew SHADL $L$ and prove that $\theta$ is a congruence relation on the equivalence class $[x]\theta$ so...

Decision Making with help of the Repeated Average Method of Fuzzy Soft Matrix -by M.K. Hasan, Md. Yasin Ali, AbedaSultana and N. K. Mitra

Decision Making with help of the Repeated Average Method of Fuzzy Soft Matrix -by M.K. Hasan, Md. Yasin Ali, AbedaSultana and N. K. Mitra

Abstract: Most of our traditional tools for formal modeling, reasoning, and computing are crisp, deterministic, and precise in character. But many complicated problems in economics, engineering, environment, social science, medical science, etc., involve data which are not always all crisp. We cannot always use the classical...

Mazur ulam problems on 2- fuzzy 2- anti normed linear space -by Thangaraj Beaula and Beulah Mariya

Mazur ulam problems on 2- fuzzy 2- anti normed linear space -by Thangaraj Beaula and Beulah Mariya

Abstract: In this paper , we introduce the concepts of 2-isometry, collinearity, Lipschitz mapping in 2-fuzzy 2-anti normed linear space and a theorem holds, when the 2-fuzzy 2-isometry which mapped to 2-fuzzy 2-anti normed linear space is affine. Keywords: 2-Strictly convex, 2-isometry, Lipschitz mapping, Area one preserving...
