• Singularities and asymptotics of solutions of the Chandrasekhar-Hamilton-Jacobi equation · 2027

  Résumé de la publication : We study the local properties of positive solutions of the equation -∆u + m |∇u|^q -e u = 0 in a punctured domain Ω \ {0} of R^N , N ≥ 2, where m is a positive parameter and q> 1. We…

• Subdiffusive fractional limit of a jump-renewal equation · 2027

  Résumé de la publication : In this paper, we consider an age-structured jump model that arises as a description of continuous time random walks with infinite mean waiting time between jumps. We prove that under a suitable rescaling, this equation converges in the long time large scale…

• Conditioning Bienaymé-Galton-Watson trees to have large sub-populations · 2026

  Résumé de la publication : We study the local limit in distribution of Bienaymé-Galton-Watson trees conditioned on having large sub-populations. Assuming a generic and aperiodic condition on the offspring distribution, we prove the existence of a limit given by a Kesten's tree associated with a certain critical…

• Spectral description of a cell growth and division equation · 2026

  Résumé de la publication : We give a refined description of the dominant spectrum of a nonlocal operator that models growth and equal mitosis of cells. More precisely we look at the spectrum in half planes at the right hand side of the first accumulation point of…

• Cubic Siegel polynomials and the bifurcation measure · 2026

  Résumé de la publication : We prove that cubic polynomial maps with a fixed Siegel disk and a critical orbit eventually landing inside that Siegel disk lie in the support of the bifurcation measure µ bif . This answers a question of Dujardin in positive. Our result…
