Higher Dimensional Moore Bounds

Hypersymmetry bounds and three-dimensional higher-spin black holes

Abstract: We investigate the hypersymmetry bounds on the higher spin black hole parameters that follow from the asymptotic symmetry superalgebra in higher-spin anti-de Sitter gravity in three spacetime dimensions. We consider anti-de Sitter hypergravity for which the analysis is most transparent. This is a osp(1|4)⊕ osp(1|4) Chern-Simons theory which contains, besides a spin-2 field, a spin-4 f...

Lower-Dimensional Bounds and a New Model for Higher-Dimensional Orthogonal Packing

Consider the feasibility problem in higher-dimensional orthogonal packing. Given a set I of d-dimensional rectangles, we need to decide whether a feasible packing in a d-dimensional rectangular container is possible. No item rotation is allowed and item edges are parallel to the coordinate axes. Typically, solution methods employ some bounds to facilitate the decision. Various bounds are known,...

The optimal perturbation bounds for the weighted Moore-Penrose inverse

In this paper, we obtain optimal perturbation bounds of the weighted Moore-Penrose inverse under the weighted unitary invariant norm, the weighted Q-norm and the weighted F -norm, and thereby extend some recent results.

Analysis of Higher Order Moore-greitzer Compressor Models

In this paper we investigate the behavior of higher order Galerkin expansions of the Moore-Greitzer model of general transients in aeroengine compression systems. We assume steady state en-trainment of the higher Fourier modes of the rotating stall cell which establishes a framework for a simpli-ed numerical analysis of the bifurcating solutions corresponding to rotating stall. For small values...
