报告摘要
We discuss the dynamics near the ground states for the 6D Fujita equation. This result presents a 6D version of the classification in a higher dimensional setting, obtained by Charles Collot-Frank Merle-Pierre Raphael (2017). In contrast to their results (they assume only that \(u_0\in \dot H^1(\mathbb{R}^n)\)), our result requires the additional integrability conditions on the initial data \(u_0\in L^2(\mathbb{R}^n)\). We also point out that the assumption \(u_0\in \dot H^1(\mathbb{R}^n)\) alone is not sufficient for the stabilization of the solution in the case \(n=6\).
