A presto, Luigi Forcella ———————————————————— Dear all, I forward you the announcement of the seminar<https://www.dm.unipi.it/en/seminar/?id=67371e1ef7cb29212bdbcc38> “Asymptotic expansions with optimal convergent rates for the convection-diffusion equation” by Ryunosuke Kusaba (Waseda University & University of Pisa). Please find the abstract below. The event will be in Aula Seminari (Dept. of Mathematics) at 5:30 PM on Thursday 21 November. Best regards, Luigi Forcella _________ Title: Asymptotic expansions with optimal convergent rates for the convection-diffusion equation Speaker: Ryunosuke Kusaba Abstract: We consider the large-time asymptotic behavior of global solutions to the convection-diffusion equation. We improve the convergent rate of the remainder for the second order asymptotic expansion established by Zuazua (1993). We also prove the optimality and non-optimality of the convergent rate by utilizing the self-similar structure of the asymptotic profile. ---------- Luigi Forcella, Assistant Professor (RTD-B, tenure-track) University of Pisa Department of Mathematics Largo Bruno Pontecorvo 5 57127 Pisa, Italy https://pagine.dm.unipi.it/forcella/index.html
