Hook Interpolations

The hook components of $V^{\otimes n}$ interpolate between the symmetric power \sym^n(V) and the exterior power $\wedge^n(V)$. When $V$ is the vector space of $k\times m$ matrices over \bbc, we decompose the hook components into irreducible GL_k(\bbc)\times GL_m(\bbc)-modules. In particular, classical theorems are proved as boundary cases. For the algebra of square matrices over \bbc, a bivariate interpolation is presented and studied.Comment: 23 pages; small change

Can the BBC survive the digital age?

The BBC is a public service broadcaster that is highly regarded by the British television audience. However, it is subject to increasing threats to its continuing viability from digital private sector television providers. A part of the threat to the BBC is the way in which it is funded through the TV licence. This article examines the threats to the survival of the BBC through a review of relevant literature and with reference to a survey conducted by the author. The research confirms the high regard in which the BBC is held by the British public and argues for its continuing existence

Predictions for squeezed back-to-back correlations of ϕϕ\phi\phi and K+K−K^+K^- in high-energy heavy-ion collisions by event-by-event hydrodynamics

We calculate the squeezed back-to-back correlation (BBC) functions of $\phi \phi$ and $K^+K^-$ for heavy-ion collisions at RHIC and LHC energies, using ($2+1$)-dimensional hydrodynamics with fluctuating initial conditions. The BBC functions averaged over event-by-event calculations for many events for the hydrodynamic sources are smoothed as a function of the particle momentum. For heavy-ion collisions of Au+Au at $\sqrt{s_{NN}}=200$ GeV, the BBC functions are larger than those for collisions of Pb+Pb at $\sqrt{s_{NN}}=2.76$ TeV. The BBC of $\phi\phi$ may possibly be observed in peripheral collisions at the RHIC and LHC energies. It is large for the smaller sources of Cu+Cu collisions at $\sqrt{s_{NN}}=200$ GeV.Comment: 16 pages, 11 figure

Tuning in: diasporas at the BBC World Service

This article looks at diaspora through the transformations of an established public service broadcaster, the BBC World Service in a fast changing landscape of global broadcasting, by considering some of the findings of the AHRC-funded Tuning In: Contact Zones at the BBC World Service, which is part of the Diasporas, Migration and Identities program. Tuning In has six themes, each of which focuses upon the role of the BBC WS: The Politics of Translation, Diasporic Nationhood, Religious Transnationalism, Sport across Diasporas, Migrating Music and Drama for Developmen
