Cari/e tutti/e vi ricordo il seguente seminario domani pomeriggio: Dear all, let me I remind you about the following talk scheduled for tomorrow afternoon: Giovanni ====================== date/time/place: Wednesday March 11, 17.00-18.00, Sala Riunioni speaker: Wladimir Neves (Universidade Federal do Rio de Janeiro) title: The Hele-Shaw free boundary limit of Buckley-Leverett System abstract: In this talk, we propose a new approach to solving the Buckley-Leverett System, which is to consider a compressible approximation model characterized by a stiff pressure law. Passing to the incompressible limit, the compressible model gives rise to a Hele-Shaw type free boundary limit of Buckley-Leverett System, and it is shown the existence of a weak solution of it. https://www.dm.unipi.it/en/seminar/?id=69a9a28d5874b2b824ec5ead ====================== (The announcement should have been included in the weekly summary, but I could not check last week summary: I simply did not find in my email.) -- ________________________________________________________ Prof. Giovanni ALBERTI Dipartimento di Matematica, Università di Pisa largo Pontecorvo 5 I-56127 Pisa ITALY e-mail: giovanni.alberti@unipi.it phone: +39 050 2213 239 virtual office: https://meet.google.com/rmt-jyke-iyw webpage: http://pagine.dm.unipi.it/alberti ________________________________________________________
