    Using the method of inverse Mellin transform, we show that the perscription dependent Borel-Laplace integral can be cast, under some conditions, into the form of a dispersion relation in the coupling constant a plane

    Pomocí metody inverzní Mellinovy transformace ukazujeme, že předpisově závislý Borel-Laplaceův integrál lze za určitých podmínek přepsat do tvaru disperzní relace v komplexní rovině vazbové konstanty a
