流体数学セミナー

第 17 回　流体数学セミナー

日　時: 2025 年 5 月 9日(金) 15時30分～ 17時
場所・教室:　お茶の水女子大学理学部1号館633教室
講演者:　中里亮介氏(信州大学)
講演題目:　Analyticity and its application to the solution of compressible Navier-Stokes-Korteweg equations with zero sound speed in scaling critical framewor
講演要旨: We consider the initial-value problem for the compressible Navier-Stokes-Korteweg equations in the d-dimensional Euclidean space R^d (d≧3).The system is well-known as the Diffuse Interface model describing the motion of a vaper-liquid mixture in a compressible viscous fluid. In this talk, we would like to handle the analyticity and time-decay estimates of the global-in-time solution around the constant equilibrium states (ρ_*,0) (ρ_*>0) of the problem under the zero sound speed case (namely, P'(ρ_*)=0, where P=P(ρ) stands for the pressure) and scaling critical settings based on Fourier-Herz spaces. If time allows, we would introduce the result on the decay estimate of the first order asymptotic formula.This talk is based on the joint work with Prof. Takayuki Kobayashi (Osaka University).
