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> 2021-06-30T00:00:00+00:00 Copyright (c) 2021 Journal of Mathematical Analysis and Modeling https://sabapub.com/index.php/jmam/article/view/274 Positive solution for a class of Caputo-type fractional differential equations 2021-06-27T07:57:54+00:00 Jayashree Patil jv.patil29@gmail.com Archana Chaudhari archubkharat@gmail.com Mohammed S Abdo msabdo1977@gmail.com Basel Hardan bassil2003@gmail.com Amol Bachhav amol.bachhav@utdallas.edu <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> 2021-06-30T00:00:00+00:00 Copyright (c) 2021 Journal of Mathematical Analysis and Modeling https://sabapub.com/index.php/jmam/article/view/276 On B- Covariant Derivative of First Order for Some Tensors in different Spaces 2021-06-06T12:38:37+00:00 Alaa A. Abdallah ala733.ala00@gmail.com A. A. Navlekar dr.navlekar@gmail.com Kirtiwant P. Ghadle ghadle.maths@bamu.ac.in <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> 2021-06-30T00:00:00+00:00 Copyright (c) 2021 Journal of Mathematical Analysis and Modeling https://sabapub.com/index.php/jmam/article/view/295 On Fuzzy Henstock-Kurzweil-Stieltjes-♦-Double Integral on Time scales 2021-06-23T19:53:34+00:00 David AFARIOGUN afrodavy720@gmail.com Adesanmi MOGBADEMU amogbademu@unilag.edu.ng Hallowed OLAOLUWA holaoluwa@unilag.edu.ng <p>We introduce and study some properties of fuzzy Henstock-Kurzweil-Stietljes-$ \Diamond $-double integral on time scales.

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> 2021-07-26T00:00:00+00:00 Copyright (c) 2021 Journal of Mathematical Analysis and Modeling
