Flexible text generation for counterfactual fairness probing
Zee Fryer, Vera Axelrod, Ben Packer +3
A common approach for testing fairness issues in text-based classifiers is through the use of counterfactuals: does the classifier output change if a sensitive attribute in the inp…
Combinatorics of the geometry of Wilson loop diagrams II: Grassmann necklaces, dimensions, and denominators
Susama Agarwala, Siân Fryer, Karen Yeats
Wilson loop diagrams are an important tool in studying scattering amplitudes of SYM theory and are known by previous work to be associated to positroids. In this paper we stu…
Combinatorics of the geometry of Wilson loop diagrams I: equivalence classes via matroids and polytopes
Susama Agarwala, Siân Fryer, Karen Yeats
Wilson loop diagrams are an important tool in studying scattering amplitudes of SYM theory and are known by previous work to be associated to positroids. We characterize the…
An algorithm to construct the Le diagram associated to a Grassmann necklace
Susama Agarwala, Sian Fryer
Le diagrams and Grassmann necklaces both index the collection of positroids in the nonnegative Grassmannian , but they excel at very different tasks: for example,…
A study in : from the geometric case book of Wilson loop diagrams and SYM
Susama Agarwala, Sian Fryer
We study the geometry underlying the Wilson loop diagram approach to calculating scattering amplitudes in the gauge theory of Supersymmetric Yang Mills (SYM) . By applying the…
Color Lie rings and PBW deformations of skew group algebras
S. Fryer, T. Kanstrup, E. Kirkman +2
We investigate color Lie rings over finite group algebras and their universal enveloping algebras. We exhibit these universal enveloping algebras as PBW deformations of skew group…
Separating Ore sets for prime ideals of quantum algebras
Siân Fryer, Milen Yakimov
Brown and Goodearl stated a conjecture that provides an explicit description of the topology of the spectra of quantum algebras. The conjecture takes on a more explicit form if the…
From Grassmann necklaces to restricted permutations and back again
Karel Casteels, Siân Fryer
We study the commutative algebras appearing in Brown and Goodearl's extension of the -stratification framework, and show that if is the single parameter q…
The Prime Spectrum of Quantum and the Poisson-prime Spectrum of its Semi-classical Limit
Siân Fryer
A bijection is defined between the prime spectrum of quantum and the Poisson prime spectrum of , and we verify that and both preserve inclusions of pr…
The -Division Ring, Quantum Matrices and Semi-classical Limits
Siân Fryer
Our aim in this thesis is to use the language of deformation-quantization to understand certain quantized algebras by looking at properties of the corresponding commutative ones, a…
The q-Division Ring and its Fixed Rings
Siân Fryer
We prove that the fixed ring of the -division ring under any finite group of monomial automorphisms is isomorphic to for the same . In a similar manner,…
