## Coamoebas and Mellin transforms

##### Abstract:

The coamoeba of a complex polynomial $f$ is defined to be the image of the hypersurface defined by $f$ under the mapping $\text{Arg}$ that sends each coordinate $z_k$ to its argument $\arg z_k$. We shall discuss the connection between coamoebas and the multidimensional Mellin transforms of rational functions.
