If you have a question about this talk, please contact Dr Andrew Treglown. Given a graph on n vertices with m edges, each of unit resistance, how small can the average resistance between pairs of vertices be? There are two very plausible extremal constructions—graphs like a star, and graphs which are close to regular—with the transition between them occurring when the average degree is 3. However, we show that there is a rather surprising construction which is better.
