Homology of systemic modules

Jaiung Jun, Kalina Mincheva, Louis Rowen

We develop the rudiments of a tropical homology theory, based on "triples" and "systems." Results include a version of Schanuel's lemma, projective dimension, the homology semi-mod…

On the Hopf algebra of multi-complexes

Miodrag Iovanov, Jaiung Jun

We introduce a general class of combinatorial objects, which we call \emph{multi-complexes}, which simultaneously generalizes graphs, multigraphs, hypergraphs and simplicial and de…

Matroid-minor Hopf algebra: a cancellation-free antipode formula and other applications of sign-reversing involutions

Eric Bucher, Chris Eppolito, Jaiung Jun +1

In this paper, we give a cancellation-free antipode formula for the matroid-minor Hopf algebra. We then explore applications of this formula. For example, the cancellation-free for…

Projective systemic modules

Jaiung Jun, Kalina Mincheva, Louis Rowen

We develop the basic theory of projective modules and splitting in the more general setting of systems. Systems provide a common language for most tropical algebraic approaches inc…

Proto-exact categories of matroids, Hall algebras, and K-theory

Christopher Eppolito, Jaiung Jun, Matt Szczesny

This paper examines the category of pointed matroids and strong maps from the point of view of Hall algebras. We show that has the…

Hopf algebras for matroids over hyperfields

Christopher Eppolito, Jaiung Jun, Matt Szczesny

Recently, M.~Baker and N.~Bowler introduced the notion of matroids over hyperfields as a unifying theory of various generalizations of matroids. In this paper we generalize the not…
