Outline of Final Research Achievements

Blow-up phenomena are typical nonlinear phenomena in several mathematical models. Here “blow-up” means that a size of the solution becomes infinity in a finite time, that is, the solution has a singularity. In this research project, we focus on blow-up curves, regional blow-up and multiple blow-up in some partial differential equations. In these phenomena it is important to understand the geometric properties of the solutions in time-space plane, the strength of the singularity(blow-up rate), and their relations. We show some numerical methods to these topics and get many numerical observations. Moreover, we show mathematical results on some of those numerical conjectures.
