Multidelayed random walks: Theory and application to the neolithic transition in Europe Fort, Joaquim Debnarayan, Jana Humet Coderch, Josep Maria Neolític -- Models matemàtics Neolithic period -- Mathematical models Rutes aleatòries (Matemàtica) Random walks We present a model in which particles (or individuals of a biological population) disperse with a rest time between consecutive motions (or migrations) which may take several possible values from a discrete set. Particles (or individuals) may also react (or reproduce). We derive a new equation for the effective rest time T˜ of the random walk. Application to the neolithic transition in Europe makes it possible to derive more realistic theoretical values for its wavefront speed than those following from the single-delayed framework presented previously [J. Fort and V. Méndez, Phys. Rev. Lett. 82, 867 (1999)]. The new results are consistent with the archaeological observations of this important historical process 2004 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion http://hdl.handle.net/10256/7702 http://hdl.handle.net/10256/7702 eng info:eu-repo/semantics/altIdentifier/doi/10.1103/PhysRevE.70.031913 info:eu-repo/semantics/altIdentifier/issn/1539-3755 info:eu-repo/semantics/altIdentifier/eissn/1550-2376 Tots els drets reservats info:eu-repo/semantics/openAccess application/pdf American Physical Society © Physical Review E, 2004, vol. 70, núm. 3, p. 031913-1 - 031913-6 Articles publicats (D-F)
