Results 1 to 10 of about 237,150 (200)
Results for area differentiations and potential differentiations are related to concepts in cosmology, and to magic(n). The shapes of a sphere and other geometries will be discussed for 3 and higher dimensions and the Poincare conjecture is interpreted ...

On the spin content of the classical massless Rarita-Schwinger system
We analyze the Rarita-Schwinger massless theory in the Lagrangian and Hamiltonian approaches. At the Lagrangian level, the standard gamma-trace gauge fixing constraint leaves a 1/2 and a 3/2 propagating Poincaré group helicities. At the Hamiltonian level,

About the geographic grid of the three-dimensional hypersphere [PDF]
According to the Poincaré conjecture (1904) proved by Grigory Perelman (2002-2003) that any simply connected compact three- dimensional manifold without edges is homeomorphic to a three- dimensional hypersphere [1], to solve the problems of visualizing ...

Is the horizon of an eternal black hole really smooth?
We point out that in many eternal black holes, including a Schwarzschild eternal black hole and an eternal black hole in AdS 5, instant folded strings are created in the past wedge and render the region just outside the horizon singular.

Local BPS invariants : enumerative aspects and wall-crossing [PDF]
We study the BPS invariants for local del Pezzo surfaces, which can be obtained as the signed Euler characteristic of the moduli spaces of stable one-dimensional sheaves on the surface S. We calculate the Poincaré polynomials of the moduli spaces for the

Spectral gap for some invariant log-concave probability measures [PDF]
We show that the conjecture of Kannan, Lov\'{a}sz, and Simonovits on isoperimetric properties of convex bodies and log-concave measures, is true for log-concave measures of the form $\rho(|x|_B)dx$ on $\mathbb{R}^n$ and $\rho(t,|x|_B) dx$ on $\mathbb{R}^{

The Global Attractor of the Allen-Cahn Equation on the Sphere
In this paper we study the attractor of a parabolic semiflow generated by a singularly perturbed PDE with a non-linear term given by a bistable potential, in an oval surface; the Allen-Cahn equation being a prototypical example.

With one exception, all known non-supersymmetric AdS4 and AdS5 vacua of gauged maximal supergravities that descend from string and M theory have been shown to have modes with mass below the BF bound.

Entanglement of Purification and Multiboundary Wormhole Geometries [PDF]
We posit a geometrical description of the entanglement of purification for subregions in a holographic CFT. The bulk description naturally generalizes the two-party case and leads to interesting inequalities among multi-party entanglements of ...
