초록본문(Abstract) | We consider incompressible Euler equations with bi-rotational symmetry and no-swirl condition in $\mathbb{R}^4$. Such solutions have rotational invariance with respect to two rotation axes. In this talk, we discuss local and global well-posedness of Yudovich-type solutions. The local existence follows from extending the work of Danchin [Uspekhi Mat. Nauk 62(2007), no.3, 73–94] for axisymmetric flows in $\mathbb{R}^3$. The global existence is obtained if the local-in-time solution satisfies additional decay conditions near the axes and at infinity. This is a joint work with Kyudong Choi(UNIST) and In-Jee Jeong(SNU). |
