DERIVATION OF THE ISOTROPIC DIFFUSION SOURCE APPROXIMATION (IDSA) FOR SUPERNOVA NEUTRINO TRANSPORT BY ASYMPTOTIC EXPANSIONS ∗

In this subsection and on the basis of the numerical example of the previous subsection, we study the modeling error of the isotropic diffusion source approximation compared to

The final section is dedicated to some numerical experiments comparing the results which can be obtained through a DNS approach, the cavity with magnetic walls model, and the

The main purpose of this paper is to derive the diffusion, free streaming and reaction limits in the IDSA by Chapman–Enskog and Hilbert expansions of variations of the reaction

Following the approach proposed in [8, 12], we consider the periodic Bloch-Torrey partial differential equation as a microscopic model for the (complex) transverse water

Our main contribution consists in establishing a concentration inequality whose variance matches asymptotically the carr´ e du champ, see (1.4) and Theorem 1 in what we called

We obtain non-asymptotic Gaussian concentration bounds for the difference between the invariant distribution ν of an ergodic Brownian diffusion process and the empirical distribution
