From Curves to Tropical Jacobians and Back,calize the curve and then use the weighted metric graph to compute the tropical Jacobian. Finding the abstract tropicalization of a general curve defined by polynomial equations is difficult, because an embedded tropicalization may not be faithful, and there is no known algorithm for carrying out se

,Khovanskii Bases of Cox–Nagata Rings and Tropical Geometry,rms of these generators generate the initial algebra of this Cox ring. Sturmfels and Xu provide a classification in the case of degree 4 del Pezzo surfaces by subdividing the tropical Grassmannian .. After providing the necessary background on Cox–Nagata rings and Khovanskii bases, we review the cla

Equations and Tropicalization of Enriques Surfaces,mpute the tropical homology, thus recovering a special case of the result of [.], and establish a connection between the dimension of the tropical homology groups and the Hodge numbers of the corresponding algebraic Enriques surface.
