Regularity and pointwise convergence for dispersive equations with asymptotically concave phase on Damek-Ricci spaces

Utsav Dewan

We study the Carleson's problem on Damek-Ricci spaces $S$ for dispersive equations: \begin{equation*} \begin{cases} i\frac{\partial u}{\partial t} +Ψ(\sqrt{-\mathcal{L}} )u=0\:,\:…
