Many scientific problems involve fluids in transitional regimes. Such problems are typically characterized by the occurrence of a small parameter and show a nonuniform behavior as this parameter approaches zero. The type of the limiting macroscopic equation

is different in nature from that  for finite values of the parameter. Very often when the parameter varies in different order of magnitude

one has to couple a microscopic and a macroscopic models which is often difficult. For kinetic equations that  may exhibit hydrodynamic regimes, it is then desirable to develop robust numerical schemes that can work uniformly with respect to the regime considered, from the rarefied kinetic one to the dense hydrodynamic one, in the spirit of asymptotic-preserving (AP) schemes.

This workshop aims to bring together researchers with different expertise in AP schemes for kinetic and related problems. Our goal is to assess the current state-of-arts of AP schemes in various applications, and to foster  new collaborations. A particular focus will be made on the theoretical foundations and new and  practical applications of these techniques. Lots of time will be available for group discussions.
