SUMMARY:Conservation laws on a star-shaped network
DESCRIPTION:Next Thursday March 2, 2023:\nEvent: FAU DCN-AvH Seminar\nOrganized by: FAU DCN-AvH, Chair for Dynamics, Control and Numerics – Alexander von Humboldt Professorship at FAU, Friedrich-Alexander-Universität Erlangen-Nürnberg (Germany)\nTitle: Conservation laws on a star-shaped network\nSpeaker: Prof. Dr. Carlotta Donadello\nAffiliation: Université de Franche-Comté (France)\nAbstract. Hyperbolic conservation laws defined on oriented graphs are widely used in the modeling of a variety of phenomena such as vehicular and pedestrian traffic, irrigation channels, blood circulation, gas pipelines, structured population dynamics.\nFrom the point of view of the mathematical analysis each of these situations demands for a different definition of admissible solution, encoding in particular the node coupling between incoming and outgoing edges which is the most coherent with physical observations.\nA comprehensive study of the necessary and sufficient properties of the coupling conditions which lead to well-posedness of the corresponding admissible solutions is available in the framework of conservation laws with discontinuous flux, which can be seen as a simple 1-1 network, see (2).\nA similar theory for conservation laws on star-shaped graph is at its beginning.\nIn particular, the characterization of family of solutions obtained as limits of regularizing approximations, such as vanishing viscosity limits, is still a partially open problem.\nIn this talk we’ll provide a general introduction to the topic, an overview of the most recent results and some explicit examples.\nWHERE?\nOnline:\nZoom meeting link\nMeeting ID: 614 4658 159 | PIN code: 914397\nThis event on LinkedIn\n \nBibliography\n(1) Boris P.
