Topology of the Bend Loci of Convex Piecewise Linear Functions

Jidong Wang

This short article serves as the appendix for [Tran and Wang, 2022]. We prove that a complete intersection of $n$ generic polyhedral hypersurfaces in $R^{d}$ is $(d - n - 1)$ -co…

Equivariant cohomology and conditional oriented matroids

Galen Dorpalen-Barry, Nicholas Proudfoot, Jidong Wang

We give a cohomological interpretation of the Heaviside filtration on the Varchenko--Gelfand ring of a pair $(A, K)$ , where $A$ is a real hyperplane ar…

Minimal Representations of Tropical Rational Functions

Ngoc Mai Tran, Jidong Wang

This paper studies the following question: given a piecewise-linear function, find its minimal algebraic representation as a tropical rational signomial. We put forward two differe…
