Remark on global existence of solutions to the 1D compressible Euler equation with time-dependent damping

Yuusuke Sugiyama

In this paper, we consider the 1D compressible Euler equation with the damping coefficient $λ / (1 + t)^{μ}$ . Under the assumption that $0 \leq μ < 1$ and $λ > 0$ or $μ = 1$ and $λ > 2$ , we prov…

Optimal estimates for far field asymptotics of solutions to the quasi-geostrophic equation

Masakazu Yamamoto, Yuusuke Sugiyama

The initial value problem for the two dimensional dissipative quasi-geostrophic equation of the critical and the supercritical cases is considered. Anomalous diffusion on this equa…
