Convex Geometry and Stoichiometry
Jer-Chin, Chuang
We demonstrate the benefits of a convex geometric perspective for questions on chemical stoichiometry. We show that the balancing of chemical equations, the use of "mixtures" to ex…

Analytic subdivision invariants
Jer-Chin Chuang
This paper introduces an inner product on chain complexes of finite simplicial complexes that is well-adapted to the harmonic study of subdivisions. Its definition utilizes a decom…

Subdivisions and transgressive chains
Jer-Chin Chuang
Combinatorial transgressions are secondary invariants of a space admitting triangulations. They arise from subdivisions and are analogous to transgressive forms such as those arisi…
