5维能量临界wave equation多孤立子的构造

Construction of multi-solitons for the energy-critical wave equation in dimension 5

Yvan Martel, Frank Merle

摘要:

构造了5维聚焦能量临界非线性波动方程的任意速度的2-孤子。对于任意K >2的K-孤子,当速度共线时,存在性结果也成立。构造的主要困难是由于单个孤子的缓慢空间衰减导致的孤子之间的强相互作用。这是在与其他非线性模型(如广义KdV和非线性薛定谔方程在能量亚临界情况下),其中的相互作用是指数小的时间,由于孤子的指数衰减以前的多孤子的构造。

英文摘要:

We construct 2-solitons of any speed of the focusing energy-critical nonlinear wave equation in dimension 5. The existence result also holds for the case of K-solitons, for any K >2, assuming that the speeds are collinear. The main difficulty of the construction is the strong interaction between the solitons due to the slow spatial decay of the single soliton. This is in contrast with previous constructions of multi-solitons for other nonlinear models (like generalized KdV and nonlinear Schrodinger equations in energy subcritical cases), where the interactions are exponentially small in time due to the exponential decay of the solitons.
