Complexity, Volume 2024, Issue 1, 2024.Lassa fever is an acute viral hemorrhagic disease that affects humans and is endemic in various West African nations. In this study, a fractional‐order model is constructed using the Caputo operator for SEIR‐type Lassa fever transmission, including the control strategy.

Stability of rotating supermassive stars in presence of dark matter background [PDF]
, 1997 Stability of supermassive stars embedded in hot dark matter is investigated on the base of the energetic method. Stability effect of dark mater is compared with rotational stabilization and preference of the last factor is advocated.

Hyers-Ulam Stability of Bessel Equations
, 2018 We analyse different kinds of stabilities for the Bessel equation and for the modified Bessel equation with initial conditions. Sufficient conditions are obtained in order to guarantee Hyers-Ulam-Rassias, $ $-semi-Hyers-Ulam and Hyers-Ulam stabilities for those equations. Those sufficient conditions are obtained based on the use of integral techniques

On the Hyers-Ulam Stability of ψ-Additive Mappings
Journal of Approximation Theory, 1993 AbstractLet E1 be a real normed vector space and E2 a real Banach space. S. M. Ulam posed the problem: When does a linear mapping near an approximately additive mapping ƒ: E1 → E2 exist? We give a new generalized solution to Ulam′s problem for ψ-additive mappings. Some relations with the asymptotic differentiability are also indicated.

Journal of Applied Mathematics, Volume 2024, Issue 1, 2024.In this paper, the sequential conformable Langevin‐type differential equation is studied. A representation of a solution consisting of the newly defined conformable bivariate Mittag‐Leffler function to its nonhomogeneous and linear version is obtained via the conformable Laplace transforms’ technique. Also, existence and uniqueness of a global solution
