Abstract and Applied Analysis, Volume 2026, Issue 1, 2026.Typhoid fever remains a major public health concern in many low‐ and middle‐income countries, where the co‐circulation of Salmonella Typhi and Salmonella Paratyphi, coupled with environmental contamination, sustains disease transmission. This study develops a data‐driven Caputo fractional‐order mathematical model to investigate the environmental co ...

Abstract and Applied Analysis, Volume 2026, Issue 1, 2026.Dengue fever remains a major global public health challenge, driven by urbanization, climate change, and the complex dynamics of mosquito‐borne transmission. In this study, we propose a fractional‐order host‐vector compartmental model to capture the transmission dynamics of dengue, incorporating density‐dependent mosquito recruitment, personal ...

Abstract and Applied Analysis, Volume 2026, Issue 1, 2026.This article investigates the existence, uniqueness, and stability of solutions for a class of nonlinear fractional integrodifferential equations (NLFIDEs) with nonlocal boundary conditions in Banach algebras. By employing advanced analytical techniques within the Banach algebra framework, we rigorously establish existence and uniqueness results and ...

Exploring Ecological Dynamics and Bifurcation Structure of a Prey–Predator Model
Complexity, Volume 2026, Issue 1, 2026.The present work examines the dynamical features of a discrete‐time Rosenzweig–MacArthur predator–prey system in which the predation rate is modulated by prey density. Through a combination of theoretical derivations and computational experiments, we establish the occurrence of period‐doubling (PD) and Neimark–Sacker (NS) bifurcations, both of which ...

, 2016 We propose a new approach called Hyers-Ulam programming to discriminate whether a generalized linear functional equation, with the form for functions from a normed space into a Banach space, has the Hyers-Ulam stability or not. Our main result is that if
