A Blowup Solution of Multispeed Klein-Gordon System in Space Dimension Two with Small Initial Data

Analysis of PDEs 2024-02-07 v1

Abstract

We find an example to illustrate that the first nondegeneracy condition of (1.2) is actually needed in proving the global exsitence of 2D multispeed Klein-Gordon system with small initial data (See [3]). We construct a collection of special Klein-Gordon dispersive relations and by iterating the corresponding profiles we can find a blowup in finite time.
