DESCRIPTION:Title: <a href="https://researchseminars.org/talk/LAGARTOS/38/
 ">Hyperbolic plane curves near the non-singular tropical limit</a>\nby Cé
 dric Le Texier (U. Toulouse) as part of (LAGARTOS) Latin American Real and
  Tropical Geometry Seminar\n\n\nAbstract\nWe determine necessary and suffi
 cient conditions for real algebraic curves near the non-singular tropical 
 limit to be hyperbolic with respect to a point\, thus generalising Speyer'
 s classification of stable curves near the tropical limit.\nIn order to ob
 tain the conditions\, we develop tools of real tropical intersection theor
 y.  \nWe introduce the tropical hyperbolicity locus and the signed tropica
 l hyperbolicity locus of a real algebraic curve near the non-singular trop
 ical limit\, and show that it satisfies a real tropical analogue of convex
 ity.\nIn the case of honeycombs\, we characterise the tropical hyperbolici
 ty locus in terms of the set of twisted edges on the tropical limit.\n
