This class of Lie bialgebras is closed under the operations of taking the dual and the Drinfel’d double.  ...  Let D(g) = g+g* be the Drinfel’d double of g, i*: g* — D(g) be the corresponding natural embedding and G’ be the subgroup of a double D(G) with Lie algebra Lie(G’) = i*(g*) C D(g). It was shown by M.  ...

Following Drinfel’d the authors consider a category # whose objects are g-modules and whose morphisms Hom,g(U, W) = Hom(U, W )[A] are formal power series with co- efficients in Hom( U, W ).  ...  He uses the above decomposition to construct a neighborhood U of the identity in G.  ...

Towards a dual spin network basis for (3+1)d lattice gauge theories and topological phases

Clement Delcamp, Bianca Dittrich
2018 Journal of High Energy Physics  
We distinguish in particular a dual pair of boundary conditions, namely of electric type and of magnetic type.  ...  This can be used to consider a generalization of Ocneanu's tube algebra in order to reveal the algebraic structure of the excitations associated with certain 3d manifolds.  ...  of Research, Innovation and Science.  ...

Twisted noncommutative equivariant cohomology: Weil and Cartan models [article]

Lucio Cirio
2009 arXiv   pre-print
The construction is suggested by the noncommutative Weil algebra of Alekseev and Meinrenken; we show that one can implement a Drinfel'd twist of their models in order to take into account the noncommutativity  ...  We propose Weil and Cartan models for the equivariant cohomology of noncommutative spaces which carry a covariant action of Drinfel'd twisted symmetries.  ...  This homomorphism can be constructed for a very  ...

Fusion basis for lattice gauge theory and loop quantum gravity

Clement Delcamp, Bianca Dittrich, Aldo Riello
2017 Journal of High Energy Physics  
These excitations are classified by the irreducible representations of the Drinfel'd double of the gauge group, and can be readily "fused" together by studying the tensor product of such representations  ...  In a follow-up work, we will exploit this notion to provide a new definition of entanglement entropy for these theories.  ...  Research at Perimeter Institute is supported by the Government of Canada through the Department of Innovation, Science Open Access.  ...

91m:58012 The idea of Woronowicz (and Drinfel’d) is that, since the cat- egory of groups is rigid under deformations, the quantum de- formations should instead be made in some dual category, e.g., functions  ...  The computational virtue of this construction is that identities can be formulated in terms of diagrams (like Feyn- man diagrams, and yet completely different).  ...

2011 Electronic Research Announcements of the American Mathematical Society  
We show that the Manin triple characterization of Lie bialgebras in terms of the Drinfel'd double may be extended to arbitrary Poisson manifolds and indeed Lie bialgebroids by using double cotangent bundles  ...  This is achieved in terms of an abstract notion of double Lie algebroid (where "double" is now used in the Ehresmann sense) which unifies many iterated constructions in differential geometry.  ...  It is in the same sense that we say that Drinfel'd doubles and Ehresmann doubles are coextensive: Theorem 4.5 shows that the Drinfel'd double of a Lie bialgebroid has a double structure in the sense of  ...

A simplicial complex of Nichols algebras [article]

Michael Cuntz, Simon Lentner
2016 arXiv   pre-print
We translate the concept of restriction of an arrangement in terms of Hopf algebras.  ...  As applications, some of these Nichols algebras provide Weyl groupoids which do not arise for Nichols algebras over finite groups and in fact we realize all root systems of finite Weyl groupoids of rank  ...  As a second application, we note that quantum groups u q (g) (and other pointed Hopf algebras [AY13] ) can be obtained from a Drinfel'd double construction.  ...

Quantum algebras as quantizations of dual Poisson–Lie groups

The puzzle of global Double Field Theory: open problems and the case for a Higher Kaluza-Klein perspective [article]

Luigi Alfonsi
2020 arXiv   pre-print
The history of the geometry of Double Field Theory is the history of string theorists' effort to tame higher geometric structures.  ...  In arXiv:1912.07089 [hep-th] we proposed that the global doubled space is not a manifold, but the total space of a bundle gerbe.  ...  However, as we will see, Born geometry is still extremely efficient in dealing with doubled group manifold and, in particular, Drinfel'd doubles.  ...
