  • Scaling is Failed to parse (SVG (MathML can be enabled via browser plugin): Invalid response ("Math extension cannot connect to Restbase.") from server "https://en.wikipedia.org/api/rest_v1/":): {\displaystyle s=1} . Thus this equation is energy-critical.
  • LWP for Failed to parse (SVG (MathML can be enabled via browser plugin): Invalid response ("Math extension cannot connect to Restbase.") from server "https://en.wikipedia.org/api/rest_v1/":): {\displaystyle s \geq 1} by Strichartz estimates (see e.g. LbSo1995; earlier references exist)
    • When Failed to parse (SVG (MathML can be enabled via browser plugin): Invalid response ("Math extension cannot connect to Restbase.") from server "https://en.wikipedia.org/api/rest_v1/":): {\displaystyle s=1} the time of existence depends on the profile of the data and not just on the norm.

  • GWP for Failed to parse (SVG (MathML can be enabled via browser plugin): Invalid response ("Math extension cannot connect to Restbase.") from server "https://en.wikipedia.org/api/rest_v1/":): {\displaystyle s=1} in the defocussing case (Gl1990, Gl1992). The main new ingredient is energy non-concentration (Sw1988, Sw1992).
    • Further decay estimates and scattering were obtained in BaSa1998, Na1999d, Ta2006; global Lipschitz dependence was obtained in BaGd1997.
    • For smooth data GWP and scattering was shown in Gl1992; see also SaSw1994
    • For radial data GWP and scattering was shown in Sw1988
    • For data with small energy this was shown for general quintic non-linearities (and for either NLW or NLKG) in Ra1981.
    • Global weak solutions can be constructed by general methods (e.g. Sr1989, Sw1992); uniqueness was shown in Kt1992
    • In the focussing case there is blowup from large data by the ODE method.
    • When there is a convex obstacle GWP for smooth data is known SmhSo1995.
