Abstract
We consider different types of (local) products f 1 f 2 in Fourier Lebesgue spaces. Furthermore, we prove the existence of such products for other distributions satisfying appropriate wave-front properties. We also consider semi-linear equations of the form
with appropriate polynomials P and G, where J k denotes the k-jet of f. If the solution locally belongs to appropriate weighted Fourier Lebesgue space \({\fancyscript{F}L^q_{(\omega )} (\mathbf{R}^d)}\) and P is non-characteristic at (x 0, ξ 0), then we prove that \({(x_0,\xi_0)\not \in {\rm WF}_{\fancyscript{F}L^q_{(\widetilde {\omega })}} (f)}\), where \({\widetilde{\omega }}\) depends on ω, P and G.
