Titre Algebraicity in wall-crossing formulas and tropical geometry
Date18/06/2019
Horaire14:00 à 15:00
RésumeWall-crossing formulas proposed in a joint paper with Maxim Kontsevich (arXiv:0811.2435) for the purposes of Donaldson-Thomas theory can be explained in terms of the notion of stability data on graded Lie algebras introduced in the loc.cit. By interpreting wall-crossing formulas as gluing of a non-archimedean analytic space from standard tube domains one can approach the question of algebraicity of series which appears in the story. I plan to discuss this circle of ideas and its relationship to tropical geometry
