Galilei and Huygens: Music and science
Athanase Papadopoulos
Vincenzo Galilei and Constantijn Huygens were both humanists and eminent musicians, the former from the late Renaissance and the latter from the early Modern era. Their respective…
Abundance ties: Nephele and the globular cluster population accreted with Cen. Based on APOGEE DR17 and Gaia EDR3
Giulia Pagnini, Paola Di Matteo, Misha Haywood +8
The peculiar Galactic globular cluster Centauri (NGC 5139) has drawn attention for its unique features - such as a high stellar mass and a broad distribution of chemical elemen…
The earthquake metric on Teichm{ü}ller space
Yi Huang, Ken'ichi Ohshika, Huiping Pan +1
This is the first paper to systematically study the earthquake metric, an asymmetric Finsler metric on Teichm{ü}ller space introduced by Thurston. We provide proofs for several ass…
Simulating nearby disc galaxies on the main star formation sequence I. Bar formation and the building of the central gas reservoir
Pierrick Verwilghen, Eric Emsellem, Florent Renaud +14
Past studies have long emphasised the key role played by galactic stellar bars in the context of disc secular evolution, via the redistribution of gas and stars, the triggering of…
From giant clumps to clouds IV: extreme star-forming clumps on top of universal cloud scaling relations in gas-rich galaxies
Florent Renaud, Oscar Agertz, Alessandro B. Romeo
The clumpy nature of gas-rich galaxies at cosmic noon raises the question of universality of the scaling relations and average properties of the star-forming structures. Using cont…
Taking Music Seriously: on the Dynamics of 'Mathemusical' Research with a Focus on Hexachordal Theorems
Moreno Andreatta, Corentin Guichaoua, Nicolas Juillet
After presenting the general framework of 'mathemusical' dynamics, we focus on one music-theoretical problem concerning a special case of homometry theory applied to music composit…
A branching model for intergenerational telomere length dynamics
Athanasios Benetos, Olivier Coudray, Anne Gégout-Petit +3
We build and study an individual based model of the telomere length's evolution in a population across multiple generations. This model is a continuous time typed branching process…
Singularities and clusters
Vladimir Fock
The aim of this note is to describe a geometric relation between simple plane curve singularities classified by simply laced Cartan matrices and cluster varieties of finite type al…
Conic singularities and immediate transversality
Francois Laudenbach
I introduced the notion of immediate transversality in a recent paper on -structures on Morse complexes. I the present chapter, I prove that immediate transversality hold…
Pre-supernova feedback sets the star cluster mass function to a power law and reduces the cluster formation efficiency
Eric P. Andersson, Mordecai-Mark Mac Low, Oscar Agertz +2
The star cluster initial mass function is observed to have an inverse power law exponent around 2, yet there is no consensus on what determines this distribution, and why some vari…
Honda-Huang's work on contact convexity revisited
Yakov Eliashberg, Dishant Pancholi
Following the overall strategy of the paper ``Convex hypersurfaces in contact topology" by Ko Honda and Yang Huang on contact convexity in high dimensions, we present a simplified…
Ideal triangles, hyperbolic surfaces and the Thurston metric on Teichm{ü}ller space
Athanase Papadopoulos
These are notes on the hyperbolic geometry of surfaces, Teichm{ü}ller spaces and Thurston's metric on these spaces. They are associated with lectures I gave at the Morningside Cent…
Math{é}matiques, musique et cosmologie : A partir du Tim{é}e de Platon
Athanase Papadopoulos
Based on Plato's Timaeus, we present some reflections on music, cosmology and mathematics and their mutual influence.The article is dedicated to the composer Walter Zimmermann. The…
A glimpse into Thurston's work
Ken'Ichi Ohshika, Athanase Papadopoulos
We present an overview of some significant results of Thurston and their impact on mathematics. The final version of this paper will appear as Chapter 1 of the book "In the traditi…
A survey on Polynomial in momenta integrals for billiard problems
Michael, Bialy, Andrey E. Mironov
In this paper we give a short survey of recent results on algebraic version of the Birkhoff conjecture for integrable billiards on surfaces of constant curvature. We also discuss i…
Algebraic non-integrability of magnetic billiards
Michael, Bialy, Andrey E. Mironov
We consider billiard ball motion in a convex domain of the Euclidean plane bounded by a piece-wise smooth curve influenced by the constant magnetic field. We show that if there exi…
Algebraic Birkhoff conjecture for billiards on Sphere and Hyperbolic plane
Michael, Bialy, Andrey E. Mironov
We consider a convex curve lying on the Sphere or Hyperbolic plane. We study the problem of existence of polynomial in velocities integrals for Birkhoff billiard inside the dom…
Integrable geodesic flows on 2-torus: formal solutions and variational principle
Michael, Bialy, Andrey E. Mironov
In this paper we study quasi-linear system of partial differential equations which describes the existence of the polynomial in momenta first integral of the integrable geodesic fl…
A remark on the number of invisible directions for a smooth Riemannian metric
Michael, Bialy
In this note we give a construction of a smooth Riemannian metric on R^n which is standard Euclidean outside a compact set K and such that it has N = n(n + 1)=2 invisible direction…
New Semi-Hamiltonian hierarchy related to integrable magnetic flows on surfaces
Michael, Bialy, Andrey Mironov
We consider magnetic geodesic flows on the 2-torus. We prove that the question of existence of polynomial in momenta first integrals on one energy level leads to a Semi-Hamiltonian…
Cubic and Quartic integrals for geodesic flow on 2-torus via system of Hydrodynamic type
Michael, Bialy, Andrey Mironov
In this paper we deal with the classical question of existence of polynomial in momenta integrals for geodesic flows on the 2-torus. For the quasi-linear system on coefficients of…
