Query: Large expanders in high genus unicellular maps   We study large uniform random maps with one face whose genus grows linearly
with the number of edges. They can be seen as a model of discrete hyperbolic
geometry. In the past, several of these hyperbolic geometric features have been
discovered, such as their local limit or their logarithmic diameter. In this
work, we show that with high probability such a map contains a very large
induced subgraph that is an expander.
