The generalized Hodge and Bloch conjectures are equivalent for general complete intersections
The generalized Hodge Bloch conjectures general complete intersections Algebraic Geometry
2011/9/5
Abstract: Let $X$ be a smooth complex projective variety with trivial Chow groups. (By trivial, we mean that the cycle class is injective.) We show (assuming the Lefschetz standard conjecture) that if...
Odyssey 2 : A mission toward Neptune and Triton to test General Relativity
Odyssey mission Neptune Triton General Relativity
2011/10/18
Odyssey 2 will be proposed in December 2010 for the next call of M3 missions for Cosmic Vision 2015-2025. This mission, under a Phase 0 study performed by CNES, will aim at Neptune and Triton. Two set...
Modeling near-field radiative heat transfer from sharp objects using a general 3d numerical scattering technique
Modeling near-field radiative heat transfer sharp objects 3d numerical scattering technique
2011/8/4
Abstract: We examine the non-equilibrium radiative heat transfer between a plate and finite cylinders and cones, making the first accurate theoretical predictions for the total heat transfer and the s...
Spectral Singularities of a General Point Interaction
Complex potential spectral singularity point interaction PT -symmetry
2011/8/31
Abstract: We study the problem of locating spectral singularities of a general complex point interaction with a support at a single point. We also determine the bound states, examine the special cases...
Interference Networks with General Message Sets: A Random Coding Scheme
Interference Networks General Message Sets Broadcast Channel Mutiple Access Channel
2011/8/31
Abstract: In this paper, the Interference Network with General Message Sets (IN-GMS) is introduced in which several transmitters send messages to several receivers: Each subset of transmitters transmi...
Coupled-wave model for square-lattice photonic-crystal lasers with TE polarization -- a general approach
Coupled-wave model square-lattice photonic-crystal lasers TE polarization
2011/8/3
Abstract: A general coupled-wave model is presented for square-lattice photonic crystal (PC) lasers with transverse-electric polarization. This model incorporates the high-order coupling effects that ...
Path properties and regularity of affine processes on general state spaces
affine processes path properties regularity Markov semimartingales
2011/8/30
Abstract: We provide a new proof for regularity of affine processes on general state spaces by methods from the theory of Markovian semimartingales. On the way to this result we also show that the def...
Abstract: We construct the manifestly N=4 supersymmetric off-shell superfield "master" action for any number n of the N=4 supermultiplets (4, 4, 0) described by harmonic analytic superfields q^{+a}(\z...
On General Form of N-fold Supersymmetry
N-fold supersymmetry Weak quasi-solvability Linear differential operators Intertwining relations
2011/8/25
Abstract: We analyze general structure of N-fold supersymmetry which provides a systematic framework to construct weakly quasi-solvable quantum mechanical systems. Main ingredients of our analysis are...
In recent years there has been an outpouring of work at the intersection of socialmovement studies and organizational theory. While we are generally in sympathywith this work, we think it implies a fa...
General conditions for scale-invariant perturbations in an expanding universe
General conditions scale-invariant perturbations expanding universe
2011/9/29
We investigate the general properties of expanding cosmological models which generate scale-invariant curvature perturbations in the presence of a variable speed of sound. We show that in an expanding...
On the Local Existence for the Characteristic Initial Value Problem in General Relativity
Characteristic Initial Value Problem General Relativity Analysis of PDEs
2011/9/29
Abstract: Given a truncated incoming null cone and a truncated outgoing null cone intersecting at a two sphere $S$ with smooth characteristic initial data, a theorem of Rendall shows that the vacuum E...
GRAVITAS : General Relativistic Astrophysics VIa Timing And Spectroscopy: An ESA M3 mission proposal
General Relativistic Astrophysics Spectroscopy mission proposal
2011/9/28
GRAVITAS is an X-ray observatory, designed and optimised to address the ESA Cosmic Vision theme of "Matter under extreme conditions". It was submitted as a response to the call for M3 mission proposal...
General-relativistic model of hot accretion flows with global Compton cooling

2011/9/28
We present a model of optically thin, two-temperature, accretion flows using an exact Monte Carlo treatment of global Comptonization, with seed photons from synchrotron and bremsstrahlung emission, as...

Abstract: Let $G$ be a filtered Lie conformal algebra whose associated graded conformal algebra is isomorphic to that of general conformal algebra $gc_1$. In this paper, we prove that $G\cong gc_1$ or...
