If you have a question about this talk, please contact Johannes Carmesin. Delta-matroids were introduced by Bouchet in the late 1980s but, until recently, have not been studied a great deal since. Examples of them arise from ribbon graphs and matrices, in much the same way as matroids arise from graphs and matrices. In this talk we will give a gentle introduction to delta-matroids illustrated by their connections with ribbon graphs. We will also describe joint work with Daryl Funk and Dillon Mayhew giving bounds on the number of labelled delta-matroids. (There will not be too much matroid theory!)
