Homogeneous Hermitian holomorphic vector bundles and the Cowen-Douglas class over bounded symmetric domains

It is known that all the vector bundles of the title can be obtained by holomorphic induction from representations of a certain parabolic group on finite dimensional inner product spaces. The representations, and the induced bundles, have composition series with irreducible factors. We give a condition under which the bundle and the direct sum of its irreducible constituents are intertwined by an equivariant constant coefficient differential operator. We show that in the case of the unit ball in $\mathbb C^2$ this condition is always satisfied. As an application we show that all homogeneous pairs of Cowen-Douglas operators are similar to direct sums of certain basic pairs

Russo-Chinese energy relations: Never-ending Foreplay?

As the officially anointed Chinese President Xi Jinping is on his first state visit abroad to Moscow, speculations are abound about a long-awaited breakthrough in energy relations between the two giants. Caution, however is warranted. The honeymoon in Russo-Chinese energy relations has been elusive and progress rather slow and uneven in the past years. China’s tactical patience coupled with the division between various Russian interest groups won the upper hand for Beijing in the complex gas price negotiations, which is the key to a potential strategic energy partnership

On Weyl group equivariant maps

We prove an equivariant analogue of Chevalley's isomorphism theorem for polynomial, C(infinity) or C(omega) maps

Energy in the Eastern Mediterranean: promise or peril? Egmont Paper No. 65, May 2014

From the Introduction. In order to address the different challenges and opportunities on energy cooperation in the Eastern Mediterranean Region and Levant Basin, EGMONT – The Royal Institute for International Relations of Belgium – together with the Atlantic Council, and supported by H. E. Belgian Minister for Foreign Affairs Didier Reynders, opened an expert dialogue in 2013 in order to look at how the management of the new energy resources could act as a vector of cooperation instead of conflict between the concerned countries. The activities have targeted finding new possibilities for cooperation on political and security challenges, energy infrastructure development, the regulatory and legal framework, environmental concerns, and bilateral and regional structures, in a manner that enhances stability and security in the region, increases European energy security, contributes to rather than hinders a comprehensive Cyprus settlement, and promotes wider regional cooperation

Das fundações locais em iniciativas comunitárias baseadas na Alemanha: Devolvendo críticas à filantropia para o local?

This article explores perceptions of local philanthropic foundations situated in community-based initiative (CBI) policies that aim to achieve educational goals through the establishment of collaborative connections between schools and multiple local actors. Although roles of philanthropy in public education are controversial, scholars have yet to rigorously consider the specific local context of CBIs. We aim to help fill this research gap by investigating the main collective orientations that underlie actions of local foundations in German CBIs. Based on semi-structured interviews with chairpersons in a south German municipality, we examine patterns of experience and attitude through application of the documentary method. The reconstructed collective orientations allow for the identification of four primary roles of philanthropy in CBIs. Notably, the addition of an advocacy role relocates a phenomenon that was previously identified as a disruptive element at a (supra-)national level. These roles suggest potential for philanthropy to engage in local education policy-making. As such, they pose pressing questions that need to be addressed by public authorities and regulators. Este artículo explora las percepciones de fundaciones filantrópicas locales situadas en políticas de iniciativa comunitaria (CBI) que buscan alcanzar objetivos educativos a través del establecimiento de conexiones colaborativas entre escuelas y múltiples actores locales. Aunque los papeles de filantropía en la educación pública son controvertidos, los estudiosos todavía necesitan considerar rigurosamente el contexto local específico de los CBI. Nuestro objetivo es ayudar a llenar esa brecha de investigación, investigando las principales orientaciones colectivas que fundamentan las acciones de las fundaciones locales en los CBIs alemanes. Con base en entrevistas semiestructuradas con presidentes de un municipio del sur de Alemania, examinamos patrones de experiencia y actitud a través de la aplicación del método documental. Las orientaciones colectivas reconstruidas permiten la identificación de cuatro papeles principales de la filantropía en los CBI. Por supuesto, el aumento de un papel de abogacía se refiere a un fenómeno que fue anteriormente identificado como un elemento disruptivo en un nivel (supra) nacional. Estas funciones sugieren potencial para que la filantropía se involucra en la formulación de políticas educativas locales. Como tal, plantean cuestiones urgentes que necesitan ser abordadas por las autoridades públicas y reguladores. Este artigo explora as percepções de fundações filantrópicas locais situadas em políticas de iniciativa comunitária (CBI) que visam alcançar objetivos educacionais através do estabelecimento de conexões colaborativas entre escolas e múltiplos atores locais. Embora os papéis da filantropia na educação pública sejam controversos, os estudiosos ainda precisam considerar rigorosamente o contexto local específico dos CBIs. Nosso objetivo é ajudar a preencher essa lacuna de pesquisa, investigando as principais orientações coletivas que fundamentam as ações das fundações locais nos CBIs alemães. Com base em entrevistas semiestruturadas com presidentes de um município do sul da Alemanha, examinamos padrões de experiência e atitude por meio da aplicação do método documental. As orientações coletivas reconstruídas permitem a identificação de quatro papéis principais da filantropia nos CBIs. Notavelmente, o acréscimo de um papel de advocacia se refere a um fenômeno que foi anteriormente identificado como um elemento disruptivo em um nível (supra) nacional. Essas funções sugerem potencial para a filantropia se engajar na formulação de políticas educacionais locais. Como tal, eles colocam questões prementes que precisam ser abordadas pelas autoridades públicas e reguladores.
