Diffusion operators in particle methods - constructing problem-independent kernel choice criteria

Continuum particle methods are numerical methods for solving partial differential equations. Their importance stems from the fact that relatively few such equations can be solved analytically. Integral operators to approximate diffusive processes are widely used in particle methods, however, alternatives exist and many parameters defining the operators can be modified. So how to choose the most suitable diffusion operator for solving a specific problem?

In my talk, I will explain the use of integral operators for approximating spatial derivatives, discuss the influence of free parameters, and present a set a problem-independent quality measures that could help in operator design.
