Mesoscopic description of hippocampal replay and metastability in spiking neural networks with short-term plasticity
Bottom-up models of functionally relevant patterns of neural activity provide an explicit link
between neuronal dynamics and computation. A prime example of functional activity …

Mean-field limits for non-linear Hawkes processes with excitation and inhibition
We study a multivariate, non-linear Hawkes process ZN on the complete graph with N
nodes. Each vertex is either excitatory (probability p) or inhibitory (probability 1− p). We take …

Global solutions to quadratic systems of stochastic reaction-diffusion equations in space-dimension two
M Leocata, J Vovelle - arxiv preprint arxiv:2404.05360, 2024 - arxiv.org
We prove the existence of global-in-time regular solutions to a system of stochastic quadratic
reaction-diffusion equations. Global-in-time existence is based on a $ L^\infty $-estimate …

White-noise driven conditional McKean–Vlasov limits for systems of particles with simultaneous and random jumps
We study the convergence of N-particle systems described by SDEs driven by Brownian
motion and Poisson random measure, where the coefficients depend on the empirical …
