Study of Hybrid Problems under Exponential Type Fractional‐Order Derivatives

Journal of Mathematics, Volume 2024, Issue 1, 2024.
In this investigation, we develop a theory for the hybrid boundary value problem for fractional differential equations subject to three‐point boundary conditions, including the antiperiodic hybrid boundary condition. On suggested problems, the third‐order Caputo–Fabrizio derivative is the fractional operator applied.

Analysis of Prey‐Predator Scheme in Conjunction with Help and Gestation Delay

Journal of Mathematics, Volume 2024, Issue 1, 2024.
This paper presents a three‐dimensional continuous time dynamical system of three species, two of which are competing preys and one is a predator. We also assume that during predation, the members of both teams of preys help each other and the rate of predation of both teams is different.

The Sequential Conformable Langevin‐Type Differential Equations and Their Applications to the RLC Electric Circuit Problems

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

Analysis of Age‐Structured Mathematical Model of Malaria Transmission Dynamics via Classical and ABC Fractional Operators

Mathematical Problems in Engineering, Volume 2024, Issue 1, 2024.
Malaria is a complex disease with many factors influencing the transmission dynamics, including age. This research analyzes the transmission dynamics of malaria by developing an age‐structured mathematical model using the classical integer order and Atangana–Baleanu–Caputo fractional operators.

Comprehensive Approach of an Implicit Hybrid Urysohn–Stieltjes Integral Inclusions via Fractal Differential Constraint

Journal of Mathematics, Volume 2024, Issue 1, 2024.
This investigation establishes the solvability of an implicit hybrid nonlinear Urysohn–Stieltjes type (IHU‐S) integral inclusion. Some sufficient conditions are assumed to prove qualitative features for the solution for this class of inclusions. A comprehensive discussion and analysis, including an example and an application, is presented to illustrate

A viability theory approach to a two-stage optimal control problem of technology adoption [PDF]

A new technology adoption problem can be modelled as a two-stage control problem, in which model parameters ("technology") might be altered at some time.
