The following multilinear estimates for the Airy equation are known:

  • We have the quintilinear estimate on R: [[references.html#CoKeStTaTk-p2 CoKeStTkTa-p2]]
  • The analogue for this on T is: [[references.html#CoKeStTaTk-p2 CoKeStTkTa-p2], [references.html#CoKeStTaTk-p3 CoKeStTkTa-p3]]
\int u^3 v^2 dx dt <~ || u ||_{1/2,1/2*}^3 || v ||_{-1/2,1/2*}^2

In fact, this estimate also holds for large period, but a loss of lambda^{0+}.
