A new approach to fractional differential equations
(Serbian Society of Heat Transfer Engineers, 2023)
In this work, we define fractional derivative of order ς > 0, with no restrictions on the domain of the function, and give its geometry. We derive some rules and properties for the proposed new approach and show that if ...
On a SEIR-type model of COVID-19 using piecewise and stochastic differential operators undertaking management strategies
(American Institute of Mathematical Sciences, 2023)
In this work, an epidemic model of a susceptible, exposed, infected and recovered SEIR-type is established for the distinctive dynamic compartments and epidemic characteristics of COVID-19 as it spreads across a population ...
