GWP in the energy norm
WP for s > sc
sc = (n - 2) / 2
Subcritical n < 4
Critical n = 4
Supercritical n > 4
NONLINEAR RELATIVISTIC FIELD THEORIES
Global Regularity
Special breakdown solutions
Global Regularity for all data, for n = 4.
Step I) Reduction to small energy
Step II) Small energy implies Global Regularity
Weak GWP for small initial data in the energy norm.
