Together with one of the organizers, Roland Schnaubelt, and the invited speaker Peer Kunstmann, Martin Spitz and I participated in the 10th Euro-Maghrebian Workshop on Evolution Equations. This series of workshops was initiated in 1999 with the aim of bringing together mathematicians from Europe and the Maghreb working on evolution equations, the first one having taken place in Marrakesh, Morocco. This time the scientists met in the small city Blaubeuren, Germany, located close to Ulm in the eastern Swabian Alb. The location of the workshop was the Heinrich-Fabri Institute of the university of Tübingen. It provided us with pleasant accommodation and a well-equipped lecture room. During the breaks many lively discussions between the participants developed and the nature in the surrounding, including the famous Blautopf, invited to go for walks.
Evolution equations, the topic of the workshop, arise naturally in many sciences like physics, chemistry and biology. They appear whenever the time rate of change of a quantity (e.g. a temperature, a mass concentration or a density of a population) depends only on the present state of the quantity. This covers a wide range of natural phenomena and leads to many different scientific questions.
During the workshop three lecture series were held, each of them consisting of three talks. Thierry Cazenave from Paris spoke about Finite time blowup in nonlinear heat, Schrödinger, and Ginzburg-Landau equation. He talked about the analysis of the first two equations and how to combine the properties of their solutions in the investigation of the solutions to the last equation. Mourad Choulli from Metz gave a lecture series about Elliptic and parabolic Cauchy problems. He was mainly concerned with stability estimates for the elliptic case and the extension of their proofs to the more complicated parabolic situation. Jürgen Saal from Düsseldorf gave insights into Systematizing the maximal regularity approach to quasilinear mixed order systems. He talked about the Newton polygon approach and anisotropic function spaces and their application to free boundary value problems. These three minicourses were accompanied by nine invited lecturers and about 20 contributed talks by the participants from Europe and Northern Africa on various topics concerning evolution equations, functional analysis, partial differential equations and inverse problems.
