Maximal Decay Inequalities for Trilinear oscillatory integrals of convolution type

Philip T. Gressman, Lechao Xiao

In this paper we prove sharp $L^{\infty }$-$L^{\infty }$-$L^{\infty }$ decay for certain trilinear oscillatory integral forms of convolution type on ${\mathbb{R}}^2$. These estimates imply ear…
