研究了三维非径向聚焦能量临界非线性薛定谔方程低于基态阈值的集中紧致性通道。经单边归一化后，一个极小临界元分为四类：有限时间、快速级联、有界尺度有限质量和残余拟孤子通道。严格排除了前三类。主要结果表明，在没有径向对称性、零动量或缓慢空间中心的情况下，每个有限质量有界尺度几乎周期解恒为零。因此，低于阈值散射的任何极小反例都必须位于残余拟孤子通道；如果其尺度有界，那么它在任何时刻都有无限质量。
英文摘要
The concentration--compactness channels below the ground-state threshold are investigated for the three-dimensional nonradial focusing energy-critical nonlinear Schrödinger equation. After one-sided normalization, a minimal critical element falls into four classes: the finite-time, rapid-cascade, bounded-scale finite-mass, and residual quasi-soliton channels. The first three classes are rigorously excluded. The main result shows, without radial symmetry, zero momentum, or a slow spatial center, that every finite-mass bounded-scale almost-periodic solution is identically zero. Consequently, any minimal counterexample to below-threshold scattering must lie in the residual quasi-soliton channel; if its scale is bounded, then it has infinite mass at every time.
