Spectral dbar equation
= Spectral dbar equation
{title2=$\partial_{\bar k}F(z,k)=S(z,k)$}
A <dbar equation> in a complex <spectral parameter>, rather than the original spatial coordinate. In spectral reconstruction, its right-hand side is transformed data. A <Cauchy-Pompeiu formula> in the spectral plane reconstructs the auxiliary function; an asymptotic coefficient or the original differential equation then recovers the spatial field.
