Abstract

In this article we consider the discretely self-similar singular solutions of the Euler equations, and the possible velocity profiles concerned not only have decaying spatial asymptotics, but also have unconventional non-decaying asymptotics. By relying on the local energy inequality of the velocity profiles and the bootstrapping method, we prove some nonexistence results and show the energy behavior of the possible nontrivial velocity profiles. For the case with non-decaying asymptotics, the needed representation formula of the pressure profile in terms of velocity profiles is also given and justified.
