## 5-local-tensions ★★

Author(s): DeVos

**Conjecture**There exists a fixed constant (probably suffices) so that every embedded (loopless) graph with edge-width has a 5-local-tension.

## A homomorphism problem for flows ★★

Author(s): DeVos

**Conjecture**Let be abelian groups and let and satisfy and . If there is a homomorphism from to , then every graph with a B-flow has a B'-flow.

Keywords: homomorphism; nowhere-zero flow; tension
