Description
In my talk I will overview our recent applications of the partial-wave (p.w.) dispersion relations written for the direct and inverse amplitudes. The requirement that the amplitude should satisfy the dispersion relation significantly constrains its possible forms and allow for a more precise determination of the resonance parameters. In particular, I will focus on the $\pi\pi$ and $\pi K$ isoscalar channels (for physical and unphysical pion mass) where broad scalar resonances reside.
