Induction for "4-connected" Matroids and Graphs

A matroid M is a pair (E,I) where E is a finite set, called the ground set of M, and I is a non-empty collection of subsets of E, called independent sets of M, such that (1) a subset of an independent set is independent;

Vizing's conjectures and related problems

In 1965, Vizing proposed three conjectures about edge chromatic critical graphs which are Vizing’s Planar Graph Conjecture, Vizing’s 2-Factor Conjecture and the conjecture about the size of edge chromatic critical graphs. In
