Sufficient reproduction numbers to prevent recurrent epidemics
Methods in Ecology and Evolution, Volume 16, Issue 6, Page 1186-1200, June 2025.Abstract Current practice in the design and evaluation of control measures in disease ecology and epidemiology, including vaccination, is largely based on reproduction numbers (RNs), which represent prognostic indices of long‐term disease transmission, both in naïve populations (basic RN) and in the presence of prior exposure or infection containment ...

Exponential stability of a kind of stochastic delay difference equations
Discrete Dynamics in Nature and Society, 2006 We present a Razumilchin-type theorem for stochastic delay difference equation, and use it to investigate the mean square exponential stability of a kind of nonautonomous stochastic difference equation which may also be viewed as an approximation of a ...

Uniqueness of solutions to integrodifferential and functional integrodifferential equations [PDF]
International Journal of Stochastic Analysis, 1998 In this paper we study a class of integrodifferential and functional integro‐differential equations with infinite delay. These problems are reformulated as abstract integrodifferential and functional integrodifferential equations. We use Nagumo type conditions to establish the uniqueness of solutions to these abstract equations.

Lax Integrability and Soliton Solutions for a Nonisospectral Integrodifferential System
Complexity, 2017 Searching for integrable systems and constructing their exact solutions are of both theoretical and practical value. In this paper, Ablowitz–Kaup–Newell–Segur (AKNS) spectral problem and its time evolution equation are first generalized by embedding a ...

Semilinear Volterra Integrodifferential Problems with Fractional Derivatives in the Nonlinearities
Abstract and Applied Analysis, 2011 A second-order semilinear Volterra integrodifferential equation involving fractional time derivatives is considered. We prove existence and uniqueness of mild solutions and classical solutions in appropriate spaces.
