@misc{10481/75199, year = {2022}, month = {4}, url = {http://hdl.handle.net/10481/75199}, abstract = {This paper proposes a review focused on exotic chemotaxis and cross-diffusion models in complex environments. The term exotic is used to denote the dynamics of models interacting with a time-evolving external system and, specifically, models derived with the aim of describing the dynamics of living systems. The presentation first, considers the derivation of phenomenological models of chemotaxis and cross-diffusion models with particular attention on nonlinear characteristics. Then, a variety of exotic models is presented with some hints toward the derivation of new models, by accounting for a critical analysis looking ahead to perspectives. The second part of the paper is devoted to a survey of analytical problems concerning the application of models to the study of real world dynamics. Finally, the focus shifts to research perspectives within the framework of a multiscale vision, where different paths are examined to move from the dynamics at the microscopic scale to collective behaviors at the macroscopic scale.}, organization = {Spanish Government RTI2018-098850-B-I00}, organization = {Junta de Andalucia European Commission PY18-RT-2422 A-FQM-311-UGR18 B-FQM-580-UGR20}, organization = {National Natural Science Foundation of China (NSFC) 12171316}, organization = {Shanghai Frontiers Science Center of Modern Analysis}, organization = {German Research Foundation (DFG) 411007140}, organization = {GZ: WI 3707/5-1}, publisher = {World Scientific}, keywords = {Keller–Segel}, keywords = {Cross diffusion}, keywords = {Multiscale problems}, keywords = {Pattern formation}, keywords = {Complex interactions}, keywords = {Blow-up}, keywords = {Well-posedness}, keywords = {Micro-macro derivation}, title = {Chemotaxis and cross-diffusion models in complex environments: Models and analytic problems toward a multiscale vision}, doi = {10.1142/S0218202522500166}, author = {Bellomo, Nicola and Soler Vizcaino, Juan Segundo}, }
