Gyula Pap: Linear matroid matching in the oracle model

Gyula Pap: Linear matroid matching in the oracle model Linear matroid matching is understood as a special case of matroid matching when the matroid is given with a matrix representation. However, for certain examples of linear matroids, the matrix representation is not given, and actuall

James Oxley: A matroid extension result

Abstract: Let (A,B) be a 3-separation in a matroid M. If M is representable, then, in the underlying projective space, there is a line where the subspaces spanned by A and B meet, and M can be extended by adding elements from this line. In general, Geelen, Gerards, and Whittle proved that

3D Plotting in Matlab

This tutorial illustrates how to generate 3D plots in Matlab. We investigate the concept of how to generate a discrete representation of a continuous, 3D function before looking at tools in Matlab to implement these concepts. Topics include but are not limited to: -plot3 -meshgrid -patch

Joseph Bonin: Delta-matroids as subsystems of sequences of Higgs lifts

Abstract: Delta-matroids generalize matroids. In a delta-matroid, the counterparts of bases, which are called feasible sets, can have different sizes, but they satisfy a similar exchange property in which symmetric differences replace set differences. One way to get a delta-matroid is to t
