Anisotropic dispersion, space competition, and the slowdown of the Neolithic transition Isern Sardó, Neus Fort, Joaquim Funcions de variables complexes Kernel, Funcions de Neolític -- Models matemàtics Equacions de reacció-difusió Kernel functions Neolithic period -- Mathematical models Reaction-diffusion equations The front speed of the Neolithic (farmer) spread in Europe decreased as it reached Northern latitudes, where the Mesolithic (huntergatherer) population density was higher. Here, we describe a reaction diffusion model with (i) an anisotropic dispersion kernel depending on the Mesolithic population density gradient and (ii) a modified population growth equation. Both effects are related to the space available for the Neolithic population. The model is able to explain the slowdown of the Neolithic front as observed from archaeological data 2024-06-14T09:36:13Z 2024-06-14T09:36:13Z 2024-06-14T09:36:13Z 2010 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion http://hdl.handle.net/10256/3469 info:eu-repo/semantics/altIdentifier/doi/10.1088/1367-2630/12/12/123002 info:eu-repo/semantics/altIdentifier/issn/1367-2630 Aquest document està subjecte a una llicència Creative Commons: Reconeixement – No comercial – Compartir igual (by-nc-sa) http://creativecommons.org/licenses/by-nc-sa/3.0/es/deed.ca info:eu-repo/semantics/openAccess IOP Institute of Physics and Deutsche Physikalische Gesellschaft New Journal of Physics, 2010, vol. 12, p.123002 Articles publicats (D-F)
