"They Come, They Fish, and They Go:” EC Fisheries Agreements with Cape Verde and SĂŁo TomĂ© e PrĂncipe
Fisheries agreements with the European Community (EC) are an important component of the fisheries sector in Cape Verde and SĂŁo TomĂ© e PrĂncipe, constituting today a key source of income for the respective fisheries administration. In spite of this, and of the fact that these agreements have been renewed several times over the past decades, challenges remain in domains such as control and communication of fishing activities, follow-up of financial counterparts, and integration of European fleets’ operations with the Cape Verdean and Santomean economies. This paper analyzes the EC fisheries agreements with Cape Verde and SĂŁo TomĂ© e PrĂncipe in terms of those domains, considering both the contents of the agreements and their practical implementation. The fisheries sector in each of these countries is reviewed, as are some of the fundamentals and criticisms of EC fisheries agreements. It is argued that the agreements with Cape Verde and SĂŁo TomĂ© e PrĂncipe will not live up to the stated objectives of sustainability and responsibility in fisheries until improvements are made to the control of EC vessels, the follow-up of funds paid by the EC, and the size and diversity of benefits accruing to the fisheries and related sectors in the two countrie
-monopoles with singularities (examples)
-monopoles are solutions to gauge theoretical equations on
-manifolds. If the -manifolds under consideration are compact, then
any irreducible -monopole must have singularities. It is then important to
understand which kind of singularities -monopoles can have. We give
examples (in the noncompact case) of non-Abelian monopoles with Dirac type
singularities, and examples of monopoles whose singularities are not of that
type. We also give an existence result for Abelian monopoles with Dirac type
singularities on compact manifolds. This should be one of the building blocks
in a gluing construction aimed at constructing non-Abelian ones.Comment: Lett Math Phys (2016
Voevodsky's mixed motives versus Kontsevich's noncommutative mixed motives
Following an insight of Kontsevich, we prove that the quotient of Voevodsky's
category of geometric mixed motives DM by the endofunctor -Q(1)[2] embeds
fully-faithfully into Kontsevich's category of noncommutative mixed motives
KMM. We show also that this embedding is compatible with the one between pure
motives. As an application, we obtain a precise relation between the Picard
groups Pic(-), the Grothendieck groups, the Schur-finitenss, and the
Kimura-finitenss of the categories DM and KMM. In particular, the quotient of
Pic(DM) by the subgroup of Tate twists Q(i)[2i] injects into Pic(KMM). Along
the way, we relate KMM with Morel-Voevodsky's stable A1-homotopy category,
recover the twisted algebraic K-theory of Kahn-Levine from KMM, and extend
Elmendorf-Mandell's foundational work on multicategories to a broader setting.Comment: This paper has been withdrawn for further analysi
Standard Model Higgs Searches at the LHC
The study of the mechanism behind electroweak symmetry breaking is one of the
main goals of the Large Hadron Collider and of its general-purpose experiments,
ATLAS and CMS. This paper reviews some of the ongoing studies by these
collaborations and, when possible, highlights the differences between
equivalent channels in both experiments.Comment: Parallel talk at ICHEP08, Philadelphia, USA, July 2008. 4 pages,
