Classification of Boundary Gravitons in AdS3 Gravity
(Springer Heidelberg, 2014-05)
We revisit the description of the space of asymptotically AdS3 solutions of pure gravity in three dimensions with a negative cosmological constant as a collection of coadjoint orbits of the Virasoro group. Each orbit ...
Symmetry insights for design of supercomputer network topologies: roots and weights lattices
(World Scientific Publishing Co. Pte. Ltd.Singapore, 2012)
We present a family of networks whose local interconnection topologies are generated by the root vectors of a semi-simple complex Lie algebra. Cartan classification theorem of those algebras ensures those families of ...
Existence and symmetries of solutions in Besov-Morrey spaces for a semilinear heat-wave type equation
(Elsevier B.V., 2015-12-01)
This paper considers a semilinear integro-differential equation of Volterra type which interpolates semilinear heat and wave equations. Global existence of solutions is showed in spaces of Besov type based in Morrey spaces, ...
Singularities of equidistants and global centre symmetry sets of Lagrangian submanifolds
(SpringerDordrecht, 2014-04)
We study the global centre symmetry set (GCS) of a smooth closed submanifold 'M POT.M'⊂'R POT.N', n≤2m . The GCS includes both the centre symmetry set defined by Janeczko (Geometria Dedicata 60:9–16, 1996) and the Wigner ...
Beautiful mirrors for a pNGB Higgs
(Springer, 2016-03)
We consider one of the most significant deviations from the Standard Model: the forward-backward asymmetry of the b-quark measured at leptonic colliders. We investigate the possibility to solve this discrepancy by introducing ...
Symmetry-preserving contact interaction model for heavy-light mesons
(Amer Inst Physics, 2016-01-01)
We use a symmetry-preserving regularization method of ultraviolet divergences in a vector-vector contact interaction model for low-energy QCD. The contact interaction is a representation of nonperturbative kernels used ...
Layout and material gradation in topology optimization of functionally graded structures: a global-local approach
(SPRINGER, 2010)
By means of continuous topology optimization, this paper discusses the influence of material gradation and layout in the overall stiffness behavior of functionally graded structures. The formulation is associated to symmetry ...
