http://system.lm-ns.org/index.php/lm-ns/article/view/1465
In this paper, we consider the initial-boundary value problem for nonlinear heat equations with nonlinear boundary conditions of the radiation type. The local well-posedness of this problem is shown by applying an abstract theory for the evolution equation governed by sub- differential operators. Moreover, a result on the uniform boundedness for time global solutions is obtained.Mitsuharu Otani, Kosuke Kitahttp://system.lm-ns.org/index.php/lm-ns/article/view/1465Sat, 18 Sep 2021 00:00:00 +0000Inexact infinite products of nonexpansive mappings with nonsummable errors
http://system.lm-ns.org/index.php/lm-ns/article/view/1460
Given a sequence of nonexpansive mappings which map a closed subset of a complete metric space into the space, we study the convergence of its inexact innite products to its common xed point set in the case where the errors are nonsummable. Previous results in this direction concerned nonexpansive self-mappings of a complete metric space and inexact iterates with summable errors.Simeon Reich, Alexander J.

http://system.lm-ns.org/index.php/lm-ns/article/view/1471
In this work, we determined the general terms of $t-$balancers, $t-$balancing numbers and Lucas $t-$balancing numbers by solving the Pell equation $2x^{2}-y^{2}=2t^{2}+4t+1$ for some integer $t\geq 1.$}Ahmet Tekcan, Samet Aydinhttp://system.lm-ns.org/index.php/lm-ns/article/view/1471Sun, 09 Oct 2022 08:05:17 +0000Fractional Differential Inclusions with Non Instantaneous Impulses and Multivalued Jump
http://system.lm-ns.org/index.php/lm-ns/article/view/1430
This paper is devoted to study the existence of solutions for a class of fractional differential inclusions with non instantaneous impulses and multivalued jump involving the Caputo fractional derivative in a Banach space. The arguments are based upon M\"{o}nch's fixed point theorem and the technique of measures of noncompactness.Mouffak Benchohra, Mehdi Slimanehttp://system.lm-ns.org/index.php/lm-ns/article/view/1430Tue, 07 Apr 2020 12:45:09 +0000Noncommutative Perspectives of Operator Monotone Functions in Hilbert Spaces
http://system.lm-ns.org/index.php/lm-ns/article/view/1458
Assume that the function f:[0,∞)→R is operator monotone in [0,∞) and has the representation f(t)=f(0)+bt+∫₀^{∞}((tλ)/(t+λ))dw(λ), where b≥0 and w is a positive measure on (0,∞). In this paper we obtained among others that P_{f}(B,P)-P_{f}(A,P) =b(B-A)+∫₀^{∞}λ²[∫₀¹P((1-t)A+tB+λP)⁻¹(B-A)┊ ┊×((1-t)A+tB+λP)⁻¹Pdt]dw(λ) for all A, B, P>0. Applications for weighted operator geometric mean and relative operator entropy are also provided.Silvestru Sever Dragomirhttp://system.lm-ns.org/index.php/lm-ns/article/view/1458Sun, 09 Oct 2022 14:09:28 +0000Last pages v41n1
