Exactness of the Fock space representation of the q-commutation relations
, 2010 We show that for all q in the interval (-1,1), the Fock representation of the q-commutation relations can be unitarily embedded into the Fock representation of the extended Cuntz algebra.

British Educational Research Journal, EarlyView.Abstract In early childhood education many researchers and professionals across the world have embraced the United Nations Convention on the Rights of the Child's requirement to include young children in decision‐making. In the context of ongoing discussion about young children's capacity to share their views and opinions about matters affecting them ...

Two-dimensional Noncommutative Gravitational Quantum Well
, 2017 In this paper we consider two kinds of noncommutative space-time commutation relations in two-dimensional configuration space and feature the absolute value of the minimal length from the generalized uncertainty relations associated to the particular ...

Commentarii Mathematici Helvetici, 2004 Consider an associative algebra of differential operators in \(n\) indeterminates (with smooth or polynomial coefficients) with respect to composition. Its subspace \(W(n)\) of vector fields (i.e. first-order differential operators) constitutes a famous Lie algebra of general Cartan type with respect to commutator.

British Educational Research Journal, EarlyView.Abstract This paper explores the challenges and opportunities surrounding the recruitment and retention of minority ethnic teachers in England. Drawing on interview data from 33 teachers and school leaders of diverse ethnic backgrounds, it investigates whether racialised barriers identified in earlier research have shifted in the current context of ...

Suppression measures of commutation failure in MIDC transmission systems
The Journal of Engineering, 2019 With the increasing of direct current (DC) transmission capacity, high-voltage DC (HVDC) location has become more and more intensive, and commutation failure has become increasingly prominent in multi-infeed DC (MIDC） transmission systems.

Journal of Algebra, 2003 The purpose of this paper is to study finite-dimensional Lie algebras over a field k of characteristic zero which admit a commutative polarization (CP). Among the many results and examples, it is shown that, if k is algebraically closed, the nilradical N of a parabolic subalgebra in A_n and C_n has such a CP.

British Educational Research Journal, EarlyView.Abstract Improving retention and graduate outcomes for students from a widening participation (WP) background is key to achieving more equitable outcomes. However, evidence suggests WP students experienced different challenges than their peers during the COVID‐19 pandemic.
