DESCRIPTION:Title: <a href="https://researchseminars.org/talk/LAGARTOS/22/
 ">Patchworking the Log-critical locus of planar curves</a>\nby Lionel Lang
  (Gävle University) as part of (LAGARTOS) Latin American Real and Tropica
 l Geometry Seminar\n\n\nAbstract\nWe will report on a recent work in colla
 boration with A. Renaudineau in which we studied the critical locus for th
 e amoeba map along families of curves defined by Viro polynomials. \nRecal
 l that for real curves\, this locus is a superset of the real part. In gen
 eral\, this locus gives informations on how the curve sits in the plane. U
 nfortunately\, not much is known on its topology besides some bounds on it
 s Betti numbers.\nWe will see that the Log-critical locus admits a Patchwo
 rking theorem. We will discuss some constructions and address the sharpnes
 s of the bounds mentioned above.\n
