Matroids and delta-matroids of graphs and embedded graphs
A. M. Dunaykin |
|
Abstract:
In this talk I will introduce matroids and delta-matroids as
combinatorial objects on which some invariants of graphs and embedded
graphs can be defined. I will also touch on the connection of
invariants of chord diagrams (orientable embedded graphs with one
vertex) with Vassiliev knot invariants. All needed definitions will be
given and the examples will be supported with pictures.
