The theory of matroids or combinatorial geometries originated in linear algebra and graph theory, and has deep connections with many other areas, including field theory, matching theory, submodular optimization, lie combinatorics, and total positivity. matroids capture the combinatorial essence that these different settings share. in recent years, the (classical, polyhedral, algebraic, and.

A tropical characterization of matroids. tropical fan is a weighted polyhedral fan with 0 tension. it has a tropical degree, and algdeg(v) = tropdeg(trop v). theorem. (fink 2013) a tropical fan has degree 1 if and only if it is a matroid fan. b.
