In the support of this newly introduced idea, we attain the algebraic properties of this function, and furthermore, in the frame of simple calculus, we explore and attain the novel kind of Ostrowski type inequalities.</p> Muhammad Tariq Jamshed Nasir Jamshed Nasir Soubhagya Kumar Sahoo Ayaz Ali Mallah Copyright (c) 2021 Journal of Mathematical Analysis and Modeling https://creativecommons.org/licenses/by/4.0 2021-06-30 2021-06-30 2 2 1 15 10.48185/jmam.v2i2.216 Positive solution for a class of Caputo-type fractional differential equations https://sabapub.com/index.php/jmam/article/view/274 <p>In this paper, we investigate the existence and uniqueness of positive solutions for a class of Caputo-type fractional differential equations with nonlocal integral boundary conditions. Our analysis based on constructing the upper and lower control functions of the nonlinear terms without having any monotone conditions except the continuity, Green function, and Schauder's (Banach's) fixed point technique on a cone. Finally, some examples are given to substantiate our main results.</p> Jayashree Patil Archana Chaudhari Mohammed S Abdo Basel Hardan Amol Bachhav Copyright (c) 2021 Journal of Mathematical Analysis and Modeling https://creativecommons.org/licenses/by/4.0 2021-06-30 2021-06-30 2 2 16 29 On B- Covariant Derivative of First Order for Some Tensors in different Spaces https://sabapub.com/index.php/jmam/article/view/276 <p>In this paper, we study the relationship between Cartan's second curvature tensor $P_{jkh}^{i}$ and $(h) hv-$torsion tensor $C_{jk}^{i}$ in sense of Berwald. Moreover, we discuss the necessary and sufficient condition for some tensors which satisfy a recurrence property in $BC$-$RF_{n}$, $P2$-Like-$BC$-$RF_{n}$, $P^{\ast }$-$BC$-$RF_{n}$ and $P$-reducible-$BC-RF_{n}$.</p> Alaa A.

This new technique is based on the combining of the Kharrat-Toma integral transform with the<br />homotopy perturbation method to find the exact or approximate solutions of both linear and nonlinear models. Several examples are illustrated to test the power and efficiency of the proposed method. Further, the<br />obtained results of the hybrid approach are implemented in Maple software.</p> Shaza Alturky GEORGE ALBERT TOMA Copyright (c) 2021 Journal of Mathematical Analysis and Modeling https://creativecommons.org/licenses/by/4.0 2021-07-26 2021-07-26 2 2 50 62
