If you have a question about this talk, please contact M.Jenssen.

I will start explaining the two main problems concerning embeddings of graphs in surfaces. Then I will explain Whitney’s characterisation of planarity in terms of abstract dual graphs from the 1930s. Can abstract duals also be used to construct embeddings in surfaces beyond the plane?
