Query: Dispersive analysis tools for $\pi\pi$ and $\pi K$ scattering   In this talk we discuss the relevance of dispersive methods and their
different applications to obtain simple but rigorous parameterizations of
pion-pion and kaon-pion scattering. We show as an example our latest dispersive
analysis of $\pi K$ scattering, where we provide simple parameterizations of
data satisfying Forward Dispersion Relations up to 1.6 GeV.
