Probabilistic analysis of the upwind scheme for transport
Francois Delarue, Frédéric Lagoutière
We provide a probabilistic analysis of the upwind scheme for multi-dimensional transport equations. We associate a Markov chain with the numerical scheme and then obtain a backward…
Inducing periodicity and chaos by negative feedback
E. Pecou, B. Cessac, G. Espinoza
This paper has been withdrawn due to an error in the proof of the main theorem.
Are biological neurons that vicious ? Or only their models ?
T. Vieville, B. Cessac
This paper has been withdrawn. Its main conclusions have been published in "On dynamics of integrate-and-fi re neural networks with conductance based synapses", arXiv:0709.4370 and…
Which 3-manifold groups are Kähler groups?
Alexandru Dimca, Alexander I. Suciu
The question in the title, first raised by Goldman and Donaldson, was partially answered by Reznikov. We give a complete answer, as follows: if G can be realized as both the fundam…
On admissible rank one local systems
A. Dimca
A rank one local system $\LL$ on a smooth complex algebraic variety is 1-admissible if the dimension of the first cohomology group $H^1(M,\LL)$ can be computed from the cohomol…
The supremum of conformally covariant eigenvalues in a conformal class
Bernd Ammann, Pierre Jammes
Let (M,g) be a compact Riemannian manifold of dimension >2. We show that there is a metric h conformal to g and of volume 1 such that the first positive eigenvalue the conformal La…
Deformation theory of representations of prop(erad)s
Sergei Merkulov, Bruno Vallette
We study the deformation theory of morphisms of properads and props thereby extending to a non-linear framework Quillen's deformation theory for commutative rings. The associated c…
Asymptotic behavior of a fourth order mean field equation with Dirichlet boundary condition
Frederic Robert, Juncheng Wei
We consider asymptotic behavior of the following fourth order equation \[ Δ^2 u= ρ\frac{e^{u}}{\int_\Om e^{u} dx} {in} \Om, u= \partial_νu=0 {on} \partial Ω\] where $\Om$ is a smoo…
Multiperiodicity in the newly discovered mid-late Be star V2104 Cygni
K. Uytterhoeven, E. Poretti, E. Rodriguez +5
We obtained the first long, homogenous time-series of V2104Cyg, consisting of 679 datapoints, with the uvbybeta photometers of Sierra Nevada and San Pedro Martir Observatories with…
AMBER on the VLTI: data processing and calibration issues
Florentin Millour, Romain Petrov, Fabien Malbet +7
We present here the current performances of the AMBER / VLTI instrument for standard use and compare these with the offered modes of the instrument. We show that the instrument is…
Sensitivity of low degree oscillations to the change in solar abundances
A. Zaatri, J. Provost, G. Berthomieu +2
Context. The most recent determination of the solar chemical composition, using a time-dependent, 3D hydrodynamical model of the solar atmosphere, exhibits a significant decrease o…
Three dimensional cooling and trapping with a narrow line
Thierry Chaneliere, Ling Xiang He, Robin Kaiser +1
The intercombination line of Strontium at 689nm is successfully used in laser cooling to reach the photon recoil limit with Doppler cooling in a magneto-optical traps (MOT). In thi…
On the classification of rank two representations of quasiprojective fundamental groups
Kevin Corlette, Carlos T. Simpson
Suppose is a smooth quasiprojective variety over $\cc$ and $ρ: π_1(X,x) \to SL(2,\cc)$ is a Zariski-dense representation with quasiunipotent monodromy at infinity. Then fac…
