Bilinear Airy estimates
Much of the bilinear estimate theory for Airy equation rests on the following ``three-wave resonance identity:
The following bilinear estimates are known:
- The -3/4+ estimate references.html#KnPoVe1996 KnPoVe1996 on R:
- The -1/2 estimate references.html#KnPoVe1996 KnPoVe1996 on T: if u,v have mean zero, then for all s >= -1/2
- Remark: In principle, a complete list of bilinear estimates could be obtained from [[references.html#Ta-p2 Ta-p2]].
