 ">Tropical ideals of projective hypersurfaces</a>\nby Alex Fink (Queen Mar
 y University of London) as part of (LAGARTOS) Latin American Real and Trop
 ical Geometry Seminar\n\n\nAbstract\nA "tropical ideal"\, defined by Macla
 gan and Rincon\, is an ideal in the tropical polynomial semiring that is a
 lso a tropical linear space (on each finite set of monomials).  A tropical
  ideal cuts out a tropical variety.  But already for projective tropical h
 ypersurfaces there can be a large family of tropical ideal structures\, mu
 ch larger even than the set of tropicalisations of classical ideals.  This
  talk will be centred on a collection of examples\, including a non-realis
 able ideal structure on a large set of tropical hypersurfaces\, and the cl
 assification of ideals of double points on the line.\n\nThis is based on j
 oint work with Jeff and Noah Giansiracusa.\n
