Non Abelian BF theories with sources and 2-D gravity

We study the interaction of non-Abelian topological $BF$ theories defined on two dimensional manifolds with point sources carrying non-Abelian charges. We identify the most general solution for the field equations on simply and multiply connected two-manifolds. Taking the particular choice of the so-called extended Poincar\'e group as the gauge group we discuss how recent discussions of two dimensional gravity models do fit in this formalism.Comment: 20 pages, Latex, To appear in Phys Rev D5

Marching for God in the global city: Public space, religion anddiasporic identities in a transnational African church

Taking the London-based brass band of a transnational Congolese church (the Kimbanguist church) as a case study, this article explores how the sonic, visible and embodied experience of religion in the public space is linked to the politics and poetics of diasporic belongings. These public performances enable Kimbanguists to claim a place and a space in the city while ‘emploting’ a particular vision of self and others in the pluralised environment of the diaspora. After discussing the literature on urban religious parades and processions, the article addresses the wider implications of the sacralisation of space and public performance of faith in terms of urban but also post-colonial centre/periphery dialectics. Finally, it reflects on the construction of diasporic and ethnic identities as well as the reinterpretation of Kimbanguist religiosity among second-generation Congolese youth in the British context
