Tropical elliptic curves in 3-space
Laura Casabella, Lars Kastner, Raluca Vlad
We classify trivalent graphs with 16 vertices and 16 edges that arise from intersecting two quadratic surfaces in tropical 3-space. There are 4,009 such graphs, representing maxima…

Subdivisions of Hypersimplices: with a View Toward Finite Metric Spaces
Laura Casabella, Michael Joswig, Lars Kastner
The secondary fan is a polyhedral fan which stratifies the regular subdivisions of the hypersimplices . We find new infinite families of rays of , and we c…
