Tensor-based modeling and computation emerge prominently with urgent demands from practical applications in the big data era. With the intrinsic sparsity in real data sets and the dimensionality reduc...
Is the five-flow conjecture almost false?
Nowhere–zero flows flow polynomial flow roots Tutte’s five–flow conjecture
2010/12/9
The number of nowhere-zero ZQ flows on a graph G can be shown to be a polynomial in Q,efining the flow polynomial G(Q). According to Tutte’s five-flow conjecture,G(5) > 0 for any bridgeless G.
