Leibniz Homology of the Affine Indefinite Orthogonal Lie Algebra [PDF]

open access: yes, 2013
In this paper, we compute the Leibniz (co)homology of the affine indefinite orthogonal Lie algebra. This calculation generalizes a result \cite[corollary 4.5]{JL} obtained by Jerry Lodder. We construct several indefinite orthogonal invariants in terms of

Scattering theory for quantum fields with indefinite metric

open access: yes, 2005
In this work, we discuss the scattering theory of local, relativistic quantum fields with indefinite metric. Since the results of Haag--Ruelle theory do not carry over to the case of indefinite metric, we propose an axiomatic framework for the ...

Simplifying indefinite fibrations on 4-manifolds [PDF]

open access: yesTransactions of the American Mathematical Society, 2017
We present explicit algorithms for simplifying the topology of indefinite fibrations on 4-manifolds, which include broken Lefschetz fibrations and indefinite Morse 2-functions.

‘A completely different space’: Teachers' perspectives on disadvantage, access to nature and outdoor learning

open access: yesBritish Educational Research Journal, EarlyView.
Abstract This study examined teachers' perspectives on how children benefit from time in nature, how disadvantage shapes access and the role of schools in facilitating such access. Drawing on interviews conducted in 2022 with 25 UK primary school teachers who participated in Generation Wild, a nature connection programme for schools in economically ...

On CR-Lightlike Product of an Indefinite Kaehler Manifold

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2011
We have studied mixed foliate CR-lightlike submanifolds and CR-lightlike product of an indefinite Kaehler manifold and also obtained relationship between them.

Nowhere Weak Differentiability of the Pettis Integral

open access: yes, 1994
For an arbitrary infinite-dimensional Banach space $\X$, we construct examples of strongly-measurable $\X$-valued Pettis integrable functions whose indefinite Pettis integrals are nowhere weakly differentiable; thus, for these functions the Lebesgue ...

Contrasting roles of school and public libraries in lower primary pupils' reading

open access: yesBritish Educational Research Journal, EarlyView.
Abstract Libraries represent an important institutional component of children's reading socialisation, yet their role is often treated as uniform despite substantial differences between school and public libraries. This study examines how visits to school and public libraries relate to pupils' reading attitudes, practices and self‐assessed reading ...

Image analysis method for measurement and prediction of intra‐matrix IgG diffusion

open access: yesBiotechnology Progress, EarlyView.
Experimental and image analysis workflow for b‐IgG diffusion in hyaluronic acid (HA) matrix. Abstract Measurement and imaging of intra‐matrix protein therapeutics diffusion is important due to the emergence of injectable biologics currently in various stages of research and clinical testing.

Indefinite Eigenvalue Problems for p-Laplacian Operators with Potential Terms on Networks

open access: yesAbstract and Applied Analysis, 2014
We address some forward and inverse problems involving indefinite eigenvalues for discrete p-Laplacian operators with potential terms. These indefinite eigenvalues are the discrete analogues of p-Laplacians on Riemannian manifolds with potential terms ...
