On the modelling of spatially heterogeneous nonlocal diffusion: deciding factors and preferential position of individuals

M Alfaro, T Giletti, YJ Kim, G Peltier, H Seo - Journal of Mathematical …, 2022 - Springer
We develop general heterogeneous nonlocal diffusion models and investigate their
connection to local diffusion models by taking a singular limit of focusing kernels. We reveal …

Local and nonlocal energy-based coupling models

G Acosta, F Bersetche, JD Rossi - SIAM Journal on Mathematical Analysis, 2022 - SIAM
In this paper we study two different ways of coupling a local operator with a nonlocal one so
that the resulting equation is related to an energy functional. In the first strategy the coupling …
