Abstract
A standard statement in undergraduate graph theory is that 'deletion and contraction are dual operations'. But this statement is only partially true, and completing it will take us on a route through graphs in surfaces to the world of delta-matroids. Along the way we'll see some of this general setting's advantages and challenges.
