A tree theorem that does not extend to cycles
Track B internal kernels, trees, and the grouped target › A tree theorem that does not extend to cycles · lines 1828–1835
For a cycle, nonzero edge covectors can circulate with zero sum at every vertex. The leaf proof is unavailable. This explains why tree admission and properness do not establish the two-cross-line product. It is not a proof that every cyclic prescription is impossible.
