The influence of parasitic modes on "weakly'' unstable multi-step Finite Difference schemes
Thomas Bellotti
Numerical analysis for linear constant-coefficients Finite Difference schemes was developed approximately fifty years ago. It relies on the assumption of scheme stability and in pa…
Causal completion of a globally hyperbolic conformally flat spacetime
Rym Smaï
In [6], Geroch, Kronheimer and Penrose introduced a way to attach ideal points to a spacetime M , defining the causal completion of M. They established that this is a topological s…
Enveloping space of a globally hyperbolic conformally flat spacetime
Rym Smaï
We prove that any simply-connected globally hyperbolic conformally flat spacetime V can be conformally embedded in a bigger conformally flat spacetime, called enveloping space of V…
Hydrodynamic limit of N-branching Markov processes
Jean Bérard, Brieuc Frénais
We consider the behaviour of branching-selection particle systems in the large population limit. The dynamics of these systems is the combination of the following three components:…
Functional central limit theorem and Marcinkiewicz strong law of large numbers for Hilbert-valued U-statistics of absolutely regular data
Davide Giraudo
In this paper, we investigate the functional central limit theorem and the Marcinkiewicz strong law of large numbers for U-statistics having absolutely regular data and taking valu…
The comonotone flow of a stochastically monotone Feller process on the real line
Jean Bérard, Brieuc Frénais
We show that any stochastically monotone Feller semigroup on R can be extended by a consistent family of order-preserving Feller semigroups on the successive powers of R. We exhibi…
Café conversations: A tribute to Norbert A'Campo
Athanase Papadopoulos
This is an intrusion in the life and the mathematics of Norbert A'Campo, intended to be a tribute to him and an acknowledgement of his impact on those who know him and his work. Th…
Pavel Florensky and his world
Athanase Papadopoulos
This is an overview of the life and works of Pavel Florensky, an important and singular figure of the period rightly described as the \emph{Silver Age of Russian mathematics}, with…
Some notes on ergodic theorem for -statistics of order for stationary and not necessarily ergodic sequences
Davide Giraudo
In this note, we give sufficient conditions for the almost sure and the convergence in of a -statistic of order built on a strictly stationary but not necessa…
Simply connectedness and hyperbolicity
Erwan Rousseau, Carlo Gasbarri, Amos Turchet +1
We generalize to arbitrary dimension our previous construction of simply connected weakly-special but not special varieties. We show that they satisfy the function field and comple…
Multi-frequency averaging and uniform accuracy towards numerical approximations for a Bloch model
Brigitte Bidégaray-Fesquet, Clément Jourdana, Léopold Trémant
We are interested in numerically solving a transitional model derived from the Bloch model. The Bloch equation describes the time evolution of the density matrix of a quantum syste…
Multi-Scenario Empirical Assessment of Agile Governance Theory: A Technical Report
Alexandre J. H. de O. Luna, Marcelo L. M. Marinho
Context: Agile Governance Theory (AGT) has emerged as a potential model for organizational chains of responsibility across business units and teams. Objective: This study aims to a…
Families of four-dimensional integrable systems with -symmetries
Yohann Le Floch, Joseph Palmer
The aim of this paper is to give new insights about families of integrable systems lifting a Hamiltonian -space. Specifically, we study one-parameter families $(M^4,ω,F_t=(J,H…
Mean-variance dynamic portfolio allocation with transaction costs: a Wiener chaos expansion approach
Areski Cousin, Jérôme Lelong, Tom Picard
This paper studies the multi-period mean-variance portfolio allocation problem with transaction costs. Many methods have been proposed these last years to challenge the famous uni-…
Real-time elastic partial shape matching using a neural network-based adjoint method
Alban Odot, Guillaume Mestdagh, Yannick Privat +1
Surface matching usually provides significant deformations that can lead to structural failure due to the lack of physical policy. In this context, partial surface matching of non-…
Timelike Hilbert geometry of the spherical simplex
Athanase Papadopoulos, Sumio Yamada
We prove the following result on the timelike spherical Hilbert geometry of simplices: Let be a simplex on the 2-sphere and the antipodal simplex. We show that th…
Posets and Fractional Calabi-Yau Categories
Frédéric Chapoton
This article deals with a relationship between derived categories of modules over some partially ordered sets and triangulated categories arising from quasi-homogeneous isolated si…
Reducing the memory usage of Lattice-Boltzmann schemes with a DWT-based compression
Clément Flint, Philippe Helluy
This paper presents a new solution to address the challenge of increasing memory usage in high-performance computing simulations of Lattice-Bolzmann or Finite-Volume schemes.Our ap…
Minimal time of magnetization switching in small ferromagnetic ellipsoidal samples
Raphaël Côte, Clémentine Courtès, Guillaume Ferrière +1
In this paper, we consider a ferromagnetic material of ellipsoidal shape. The associated magnetic moment then has two asymptotically stable opposite equilibria, of the form $\pm\ov…
Some notes on the impact of Lagrange's memoir "On the construction of geographical maps"
Athanase Papadopoulos
These are notes on the impact of Lagrange's memoir on the construction of geographical maps. We mention the relations of some ideas and questions introduced in this memoir with oth…
Natural transformations relating homotopy and singular homology functors
Benjamin Enriquez, Florence Lecomte
The category of topological spaces endowed with two marked points is equipped with two families and of functors to the category of abelian groups, index…
