DESCRIPTION:Title: <a href="https://researchseminars.org/talk/LAGARTOS/16/
 ">Polynomial properties of tropical refined invariants</a>\nby Erwan Bruga
 llé (U. Nantes) as part of (LAGARTOS) Latin American Real and Tropical Ge
 ometry Seminar\n\n\nAbstract\nTropical geometry is a useful tool in the en
 umeration of complex or real algebraic curves. Around 10 years ago Block a
 nd Göttsche proposed a kind of quantification of tropical enumerative inv
 ariants\, which are Laurent\npolynomial interpolating between complex and 
 real enumerative\ninvariants. In this talk I will review these tropical re
 fined invariants\nand their relation with classical enumerative geometry. 
 I will then\nexplain some curious polynomial behavior of the coefficients 
 of these\nrefined invariants\, providing in particular a surprising resurg
 ence\, in\na dual setting\, of the so-called node polynomials and Göttsch
 e conjecture.\n
