The theory of the quintic NLS on \R^3 is as follows.

  • Scaling is s_c = 1\,.
  • LWP is known for s \ge 1\, CaWe1990.
    • For s=1\, the time of existence depends on the profile of the data as well as the norm.
    • For s<s_c\, we have ill-posedness, indeed the H^s\, norm can get arbitrarily large arbitrarily quickly CtCoTa-p2. In the focusing case we have instantaneous blowup from the virial identity and scaling.
  • GWP and scattering for s\ge 1\, in the defocusing case CoKeStTkTa-p
    • For radial data this is in Bo1999b, Bo1999.
    • Blowup can occur in the focusing case from Glassey's virial identity.
