| Abstract: | The width of a delta-matroid is the difference in size between a maximal and minimal feasible set. We give a Rough Structure Theorem for delta-matroids that admit a twist of width one. We apply this theorem to give an excluded-minor characterisation of delta-matroids that admit a twist of width at most one. |
