On resolvent estimates for Laplace-Beltrami operators on compact manifolds
David Dos Santos Ferreira, Carlos E. Kenig, Mikko Salo
In this article we prove estimates for resolvents of Laplace-Beltrami operators on compact Riemannian manifolds, generalizing results of Kenig, Ruiz and Sogge in the Euclidea…
Tame dynamics and robust transitivity
Christian Bonatti, Sylvain Crovisier, Nicolas Gourmelon +1
One main task of smooth dynamical systems consists in finding a good decomposition into elementary pieces of the dynamics. This paper contributes to the study of chain-recurrence c…
Disjointness properties for Cartesian products of weakly mixing systems
Joanna Kułaga, François Parreau
For we consider the class JP() of dynamical systems whose every ergodic joining with a Cartesian product of weakly mixing automorphisms () can be represen…
Crowding effect on helix-coil transition: beyond entropic stabilization
A. Koutsioubas, D. Lairez, S. Combet +3
We report circular dichroism measurements on the helix-coil transition of poly(L-glutamic acid) in solution with polyethylene glycol (PEG) as a crowding agent. Using small angle ne…
Limit theorems for infinite-dimensional piecewise deterministic Markov processes. Applications to stochastic excitable membrane models
Martin G. Riedler, Michèle Thieullen, Gilles Wainrib
We present limit theorems for a sequence of Piecewise Deterministic Markov Processes (PDMPs) taking values in a separable Hilbert space. This class of processes provides a rigorous…
Topology of steady and expanding gradient Ricci solitons via f-harmonic maps
Michele Rimoldi, Giona Veronelli
In this paper we give some results on the topology of manifolds with -Bakry-Émery Ricci tensor bounded below, and in particular of steady and expanding gradient Ricci solit…
Wave Equation Numerical Resolution: a Comprehensive Mechanized Proof of a C Program
Sylvie Boldo, Francois Clement, Jean-Christophe Filliâtre +3
We formally prove correct a C program that implements a numerical scheme for the resolution of the one-dimensional acoustic wave equation. Such an implementation introduces errors…
Rubidium-87 Bose-Einstein condensate in an optically plugged quadrupole trap
Romain Dubessy, Karina Merloti, Laurent Longchambon +5
We describe an experiment to produce 87Rb Bose-Einstein condensates in an optically plugged magnetic quadrupole trap, using a blue-detuned laser. Due to the large detuning of the p…
Lyapunov spectrum of invariant subbundles of the Hodge bundle
Giovanni Forni, Carlos Matheus, Anton Zorich
We study the Lyapunov spectrum of the Kontsevich--Zorich cocycle on -invariant subbundles of the Hodge bundle over the support of a -invariant p…
Statistics on Riemann zeros
Ricardo Perez Marco
We numerically study the statistical properties of differences of zeros of Riemann zeta function and L-functions predicted by the theory of the eñe product. In particular, this pro…
Recent advances in solid-state organic lasers
Sébastien Chenais, Sebastien Forget
Organic solid-state lasers are reviewed, with a special emphasis on works published during the last decade. Referring originally to dyes in solid-state polymeric matrices, organic…
New Candidates Welcome! Possible Winners with respect to the Addition of New Candidates
Yann Chevaleyre, Jérôme Lang, Nicolas Maudet +2
In voting contexts, some new candidates may show up in the course of the process. In this case, we may want to determine which of the initial candidates are possible winners, given…
Non-uniqueness of ergodic measures with full Hausdorff dimension on a Gatzouras-Lalley carpet
Julien Barral, De-Jun Feng
In this note, we show that on certain Gatzouras-Lalley carpet, there exist more than one ergodic measures with full Hausdorff dimension. This gives a negative answer to a conjectur…
About Fokker-Planck equation with measurable coefficients and applications to the fast diffusion equation
Nadia Belaribi, Francesco Russo
The object of this paper is the uniqueness for a -dimensional Fokker-Planck type equation with non-homogeneous (possibly degenerated) measurable not necessarily bounded coeffici…
Lifshitz tails for matrix-valued Anderson models
Hakim Boumaza, Hatem Najar
This paper is devoted to the study of Lifshitz tails for a continuous matrix-valued Anderson-type model acting on $L^2(\R^d)\otimes \C^{D}$, for arbitrary and $D\ge…
Generalized Bargmann functions, their growth and von Neumann lattices
A. Vourdas, K. A. Penson, G. H. E. Duchamp +1
Generalized Bargmann representations which are based on generalized coherent states are considered. The growth of the corresponding analytic functions in the complex plane is studi…
Pre-Lie systems and obstruction to A_infty-structures over a ring
Muriel Livernet
In this note, we prove an obstruction theorem for the existence of A infinite-structures over a commutative ring R on an algebra A associative up to homotopy, in terms of the Hochs…
Thermodynamics of a Bose Einstein condensate with free magnetization
B. Pasquiou, E. Marechal, L. Vernac +2
We study thermodynamic properties of a gas of spin 3 52Cr atoms across Bose Einstein condensation. Magnetization is free, due to dipole-dipole interactions (DDIs). We show that the…
Multifractal formalism for almost all self-affine measures
Julien Barral, De-Jun Feng
We conduct the multifractal analysis of self-affine measures for "almost all" family of affine maps. Besides partially extending Falconer's formula of -spectrum outside the ra…
Derived A-infinity algebras in an operadic context
Muriel Livernet, Constanze Roitzheim, Sarah Whitehouse
Derived A-infinity algebras were developed recently by Sagave. Their advantage over classical A-infinity algebras is that no projectivity assumptions are needed to study minimal mo…
Upper motives of products of projective linear groups
Charles De Clercq
Fix a base field F, a finite field K and consider a sequence of central simple F-algebras A_1,...,A_n. In this note we provide some results toward a classification of the indecompo…
Atom interferometry and the Einstein equivalence principle
Peter Wolf, Luc Blanchet, Christian J. Bordé +3
The computation of the phase shift in a symmetric atom interferometer in the presence of a gravitational field is reviewed. The difference of action-phase integrals between the two…
The high-pressure phase of boron, γ-B28: disputes and conclusions of 5 years after discovery
Artem R. Oganov, Vladimir L. Solozhenko, Carlo Gatti +2
γ-B28 is a recently established high-pressure phase of boron. Its structure consists of icosahedral B12 clusters and B2 dumbbells in a NaCl-type arrangement (B2)δ+(B12)δ- and displ…
