Let $\mathcal{M}$ be an identifiable linear compartmental model whose Jacobian matrix is not square, so its singular locus is defined by the maximal minors of the Jacobian. An edge…

Let $\widetilde{\mathcal{M}}$ be a strongly connected linear compartmental model with at least one input and exactly one leak. A model is generically locally identifiable if its pa…

Let $\widetilde{\mathcal{M}}=(G,In,Out,Leak)$ be a strongly connected linear compartmental model with at least one input and at least one leak. A singular-locus equation $f$ is the…

Let $\mathcal{M}$ be an unidentifiable linear compartmental model. Leak-addition conjecture. If one leak is added, the resulting model $\widetilde{\mathcal{M}}$ is also unidentifia…

Let $\mathcal{M}$ be a strongly connected linear compartmental model that is generically locally identifiable, with singular-locus equation $f$. An edge $j\to i$ is dividing if its…

For a monomolecular network, let identifiability be defined using coefficient maps arising from input-output equations for output-reachable subgraphs, rather than only by the previ…
