摘要:The wave maps equation is a prototypical geometric wave equation that attracted a lot of interest in the last 30 years. Wave maps into spheres are known to develop singularities in finite time via self-similar solutions. I will discuss stability properties of self-similar solutions under optimal regularity assumptions on the data. This is joint work with David Wallauch (University of Vienna).
