Degenerations in tropical compactifications and tropical intersection theory of
Sean T. Griffin, Jake Levinson, Rohini Ramadas +1
The main result of this paper is a formula for the limit cycle of a 1-parameter family of subvarieties of a tropical compactification, expressed in terms of tropical intersections.…

Counting point configurations in projective space
Alex Fink, Navid Nabijou, Rob Silversmith
We investigate the enumerative geometry of point configurations in projective space. We define "projective configuration counts": these enumerate configurations of points in projec…

Cross-ratio degrees and triangulations
Rob Silversmith
The cross-ratio degree problem counts configurations of n points on P^1 with n-3 prescribed cross-ratios. Cross-ratio degrees arise in many corners of combinatorics and geometry, b…
