The Burau representation is not faithful for n = 5 [PDF]
Geometry & Topology, 1999 The Burau representation is a natural action of the braid group B_n on the free Z[t,t^{-1}]-module of rank n-1. It is a longstanding open problem to determine for which values of n this representation is faithful.

Learning Faithful Representations of Causal Graphs [PDF]
Proceedings of the 59th Annual Meeting of the Association for Computational Linguistics and the 11th International Joint Conference on Natural Language Processing (Volume 1: Long Papers), 2021 Learning contextual text embeddings that represent causal graphs has been useful in improving the performance of downstream tasks like causal treatment effect estimation. However, existing causal embeddings which are trained to predict direct causal links, fail to capture other indirect causal links of the graph, thus leading to spurious correlations ...

HOPF IMAGES AND INNER FAITHFUL REPRESENTATIONS [PDF]
Glasgow Mathematical Journal, 2010 AbstractWe develop a general theory of Hopf image of a Hopf algebra representation, with the associated concept of inner faithful representation, modelled on the notion of faithful representation of a discrete group. We study several examples, including group algebras, enveloping algebras of Lie algebras, pointed Hopf algebras, function algebras ...

The faithfulness question for the Burau representation [PDF]
Proceedings of the American Mathematical Society, 1993 We consider the Burau and Gassner representations of the braid groups B n {B_n} . A sufficient condition for faithfulness, involving just a pair of arcs, is shown to be necessary as well for all but at most two values of n n . In the Burau case, this implies nonfaithfulness for

Anchoring, the norm reminder effect, and the faithful representation of an entity’s financial position [PDF]
Zeszyty Teoretyczne Rachunkowości, 2021 Purpose: The aim of the paper is to verify the assumptions about the impact of the anchoring effect and the norm reminder effect in accounting decisions, in the case of the freedom of choice left by legal regulations, Methodology/approach: The study was ...

Rational and quasi-permutation representations of holomorphs of cyclic $p$-groups [PDF]
International Journal of Group Theory, 2022 For a finite group $G$, three of the positive integers governing its representation theory over $\mathbb{C}$ and over $\mathbb{Q}$ are $p(G),q(G),c(G)$.

Faithful representations with topographic maps [PDF]
Neural Networks, 1999 Topographic map algorithms that are aimed at building "faithful representations" also yield maps that transfer the maximum amount of information available about the distribution from which they receive input. The weight density (magnification factor) of these maps is proportional to the input density, or the neurons of these maps have an equal ...
