Abstract (eng)
This Master’s Thesis aims to analyze two-species biological models, describing the interaction between fibers and cells with nematic alignment, using established methods in Kinetic Theory, particularly Generalized Collision Invariants (GCI). First, an analysis of a system with only minor coupling is provided. Furthermore, the problems of defining and using GCI for more complex models, such as overdetermination, are discussed and illustrated with a simple case. Lastly, a method using the Hilbert expansion is suggested, aiming to solve these difficulties.
