q-Difference equations occupy a central role in modern mathematical analysis, providing a discrete analogue of differential equations in which the usual derivative is replaced by a finite-difference ...
Ordinary differential equations (ODEs), difference equations and dynamical systems provide complementary frameworks for modelling the evolution of quantities in continuous or discrete time. ODEs ...
Compartment models have been proposed in the 1920s as a model for the spread of an infectious disease in a society, in a famous article by Kermack and ...
