Cancellation of spurious poles in N=4 SYM: physical and geometric
Susama Agarwala, Cameron Marcott
This paper shows that not only do the codimension one spurious poles of tree level diagrams in N=4 SYM theory cancel in the tree level amplitude as expected, but their va…
Basis shape loci and the positive Grassmannian
Cameron Marcott
A basis shape locus takes as input data a zero/nonzero pattern in an matrix, which is equivalent to a presentation of a transversal matroid. The locus is defined as th…
Wilson loops in SYM do not parametrize an orientable space
Susama Agarwala, Cameron Marcott
In this paper we explore the geometric space parametrized by (tree level) Wilson loops in SYM . We show that, this space can be seen as a vector bundle over a totally non-nega…
Combinatorics of the Deodhar decomposition of the Grassmannian
Cameron Marcott
The Deodhar decomposition of the Grassmannian is a refinement of the Schubert, Richardson, and positroid stratifications of the Grassmannian. Go-diagrams are certain fillings of Fe…
