Monadic transductions and definable classes of matroids
Susan Jowett, Dillon Mayhew, Songbao Mo +1
A transduction provides us with a way of using the monadic second-order language of a structure to make statements about a derived structure. Any transduction induces a relation on…
What is a 4-connected matroid?
Nick Brettell, Susan Jowett, James Oxley +2
The {\em breadth} of a tangle in a matroid is the size of the largest spanning uniform submatroid of the tangle matroid of . A matroid is {\em weakly…
Elastic elements in 3-connected matroids
George Drummond, Zachary Gershkoff, Susan Jowett +2
It follows by Bixby's Lemma that if is an element of a -connected matroid , then either ${\rm co}(M\delete e)$, the cosimplification of $M\delete e$, or ,…
Recognising Graphic and Matroidal Connectivity Functions
Nathan Bowler, Susan Jowett
A {\em connectivity function} on a set is a function such that , that for all , and that $λ(X\cap Y)+λ(…
Connectivity Functions and Polymatroids
Susan Jowett, Songbao Mo, Geoff Whittle
A {\em connectivity function on} a set is a function such that , that for all and that $λ(X\cap Y)+λ(X…
