Neutrosophic set is a generalization of classical sets, fuzzy set, intuitionistic sets etc. A mathematical notion neutrosophic set dealing issues containing inconsistent, indeterminate and imprecise data. In this manuscript, we toss the notion of Neu

In this manuscript, we give the generalization of banach’s, Kannan’s and Chatterjee’s fixed Point theorems in neutrosophic metric spaces by using new (TS-IF⍺) contractive mappings. Also, we establish common fixed point results in neutrosophic

In this paper, we presented and proved a general Lyapunov's inequality for a class of fractional boundary problems (FBPs) involving a new fractional derivative, named $ \lambda $-Hilfer. We proved a criterion of existence which extended that of Lyapu

This study formulates a multi-objective, multi-item solid transportation issue with parameters that are neutrosophic Z-number fuzzy variables such as transportation costs, supplies, and demands. This work covers two scenarios where uncertainty in the

This paper is devoted to establishing some criteria for the existence of non-trivial solutions for a class of fractional q-difference equations involving the p-Laplace operator, which is nowadays known as Lyapunov's inequality. The method employed fo

In this paper, we apply the pseudospectral method based on the Chebyshev cardinal function to solve the parabolic partial integro-differential equations (PIDEs). Since these equations play a key role in mathematics, physics, and engineering, finding

Sufficient conditions are obtained for the nonexistence of solutions to the nonlinear pseudo-hyperbolic equation $$ u_{tt} -\Delta_{\mathbb H} u_{tt}-\Delta_{\mathbb H} u=|u|^p, \quad (\eta, t) \in \mathbb{H} \times (0,\infty), \; p>1, $$ where

We establish a new Lyapunov-type inequality for a class of fractional differential equations under Robin boundary conditions. The obtained inequality is used to obtain an interval where a linear combination of certain Mittag-Leffler functions has no

The purpose of this paper is to deal with the following nonlinear Hadamard fractional boundary value problem HDα1+ u(t) + f(t, u(t), u(t)) + g(t, u(t)) = 0,1 < t < e, 1 < α ≤ 2,u(1) = u(e) = 0, where HDα 1+ is the Hadamard fractional derivative
