Indirect Diffusion Effect in Degenerate Reaction-Diffusion Systems [PDF]
SIAM Journal on Mathematical Analysis, 2020 In this work we study global well-posedness and large time behaviour for a typical reaction--diffusion system, which include degenerate diffusion, and whose non-linearities arise from chemical reactions. We show that there is an {\it indirect diffusion effect}, i.e. an effective diffusion for the non-diffusive species which is incurred by a combination

Parameter Inference for Degenerate Diffusion Processes [PDF]
Stochastic Processes and their Applications, 2023 We study parametric inference for ergodic diffusion processes with a degenerate diffusion matrix. Existing research focuses on a particular class of hypo-elliptic SDEs, with components split into `rough'/`smooth' and noise from rough components propagating directly onto smooth ones, but some critical model classes arising in applications have yet to be

A Degenerate Cross-Diffusion System as the Inviscid Limit of a Nonlocal Tissue Growth Model [PDF]
SIAM Journal on Mathematical Analysis, 2023 In recent years, there has been a spike in the interest in multi-phase tissue growth models. Depending on the type of tissue, the velocity is linked to the pressure through Stoke's law, Brinkman's law or Darcy's law. While each of these velocity-pressure

A new order from the combination of exact coupling and the Euler scheme
AIMS Mathematics, 2022 Davie defined a Levy variant and the combination of single random variables to ensure that the diffusion matrix did not degenerate. The use of the method proposed by Davie, which is a combination of the Euler method and the exact combination, was ...

Doubly degenerate diffuse interface models of surface diffusion [PDF]
Mathematical Methods in the Applied Sciences, 2020 We discuss two doubly degenerate Cahn–Hilliard (DDCH) models for isotropic surface diffusion. Degeneracy is introduced in both the mobility function and a restriction function associated to the chemical potential. Our computational results suggest that the restriction functions yield more accurate approximations of surface diffusion.

Drift-diffusion models for the simulation of a graphene field effect transistor
Journal of Mathematics in Industry, 2022 A field effect transistor having the active area made of monolayer graphene is simulated by a drift-diffusion model coupled with the Poisson equation. The adopted geometry, already proposed in (Nastasi and Romano in IEEE Trans. Electron.

Global existence and asymptotic behavior for a nonlinear degenerate SIS model [PDF]
Opuscula Mathematica, 2013 In this paper we investigate the global existence and asymptotic behavior of a reaction diffusion system with degenerate diffusion arising in the modeling and the spatial spread of an epidemic disease.

Adaptive estimation for degenerate diffusion processes
, 2021 : We discuss parametric estimation of a degenerate diffusion system from time-discrete observations. The first component of the degenerate diffusion system has a parameter θ1 in a non-degenerate diffusion coefficient and a parameter θ2 in the drift term.
