On the maximum-minimum principle for advection-diffusion equations
The air pollution transport model is generally solved with the so-called operator splitting technique. The original
 problem is split into several subproblems and the solution of the model is obtained by solving the subproblems
 cyclically. In this paper, we analyze the advection, di...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | The air pollution transport model is generally solved with the so-called operator splitting technique. The original
problem is split into several subproblems and the solution of the model is obtained by solving the subproblems
cyclically. In this paper, we analyze the advection, diffusion and emission subproblems. These subproblems have to
possess certain qualitative properties that follow from physical considerations: nonnegativity preservation, maximumminimum
principle and maximum norm contractivity. We show that these properties are valid for the subproblems, and
we shad light on their relations.
