Global dynamics above the ground state for the energy-critical Hartree equation with radial data
Abstract
Based on the concentration-compactness-rigidity argument in KenM:NLS,KenM:NLW and the non-degeneracy of the ground state in LLTX:Nondeg,LLTX:g-Hart,LTX:Nondeg, long time dynamics for the focusing energy-critical Hartree equation with radial data have been classified when the energy E(u0)≤ E(W) in LiMZ:crit Hart,LLTX:g-Hart,MWX:Hart,MXZ:crit Hart:f rad, where W is the ground state. In this paper, we continue the study on the dynamics of the radial solutions with the energy E(u0) at most slightly larger than that of the ground states. This is an extension of the results KriNS:NLW rad, KriNS:NLW non,NakR,NakS:NLKG,NakS:book,NakS:NLS,NakS:NLKG:non,Roy on NLS, NLW and NLKG, which were pioneered by K. Nakanishi and W. Schlag in NakS:NLKG, NakS:book in the study of nonlinear Klein-Gordon equation in the subcritical case. The argument is an adaptation of the works in KriNS:NLW rad, KriNS:NLW non,NakR,Roy, the proof uses an analysis of the hyperbolic dynamics near the ground state and the variational structure far from them. The key components that allow to classify the solutions are the hyperbolic (ejection) dynamical behavior near the ground state and the one-pass lemma.
