Comparing virus incubation time in SIRC models: Deterministic versus stochastic approaches

Infectious Disease Modelling
Time delays are a fundamental feature in modeling stochastic epidemic systems, as they capture the incubation period and other physiological lags inherent in disease transmission.

Qualitative Behavior of the Solutions to Delay and Difference Equations

Вестник КазНУ. Серия математика, механика, информатика, 2018
It is noteworthy to observe that a first-order linear ordinary differential equation without delay does not possess oscillatory solutions. Therefore the investigation of oscillatory solutions is of interest for equations with delays or for the discrete

Delayed perturbation of Mittag‐Leffler functions and their applications to fractional linear delay differential equations [PDF]

Mathematical methods in the applied sciences, 2018
In this paper, we propose a delayed perturbation of Mittag‐Leffler type matrix function, which is an extension of the classical Mittag‐Leffler type matrix function and delayed Mittag‐Leffler type matrix function. With the help of the delayed perturbation
