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.
