A counterexample to McKean's conjecture for the Landau-Coulomb equation

Jonathan Junné, Raphael Winter, Havva Yoldaş

We disprove McKean's conjecture, which asserts that the entropy dissipation is monotone nonincreasing along solutions, or equivalently that the entropy is convex in time, for the s…

On a class of nonlinear BGK-type kinetic equations with density dependent collision rates

Josephine Evans, Daniel Morris, Havva Yoldaş

We consider a class of nonlinear, spatially inhomogeneous kinetic equations of BGK-type with density dependent collision rates. These equations share the same superlinearity as the…

Trend to equilibrium for run and tumble equations with non-uniform tumbling kernels

Josephine Evans, Havva Yoldaş

We study the long-time behaviour of a run and tumble model which is a kinetic-transport equation describing bacterial movement under the effect of a chemical stimulus. The experime…

Concentration in Lotka-Volterra parabolic equations: an asymptotic-preserving scheme

Vincent Calvez, Hélène Hivert, Havva Yoldaş

In this paper, we introduce and analyze an asymptotic-preserving scheme for Lotka-Volterra parabolic equations. It is a class of nonlinear and nonlocal stiff equations, which descr…

On quantitative hypocoercivity estimates based on Harris-type theorems

Havva Yoldaş

This review concerns recent results on the quantitative study of convergence towards the stationary state for spatially inhomogeneous kinetic equations. We focus on analytical resu…

A cross-diffusion system obtained via (convex) relaxation in the JKO scheme

Romain Ducasse, Filippo Santambrogio, Havva Yoldaş

In this paper, we start from a very natural system of cross-diffusion equations, which can be seen as a gradient flow for the Wasserstein distance of a certain functional. Unfortun…

Analysis of a cross-diffusion model for rival gangs interaction in a city

Alethea B. T. Barbaro, Nancy Rodriguez, Havva Yoldaş +1

We study a two-species cross-diffusion model that is inspired by a system of convection-diffusion equations derived from an agent-based model on a two-dimensional discrete lattice.…

Spectral gap for the growth-fragmentation equation via Harris's Theorem

José A. Cañizo, Pierre Gabriel, Havva Yoldaş

We study the long-time behaviour of the growth-fragmentation equation, a nonlocal linear evolution equation describing a wide range of phenomena in structured population dynamics.…

Asymptotic behaviour of neuron population models structured by elapsed-time

José A. Cañizo, Havva Yoldaş

We study two population models describing the dynamics of interacting neurons, initially proposed by Pakdaman, Perthame, and Salort (2010, 2014). In the first model, the structurin…
