摘要
In this paper, we consider the Cauchy problem for the two dimensional rotational compressible Euler equations with nonzero relatively vorticity. Lifespan of smooth solutions is obtained by using the ghost weight energy estimate, global smooth solutions to the two dimensional rotational compressible Euler equations with zero relatively vorticity and the bootstrapping argument. The result clarifies the influence of nonzero relatively vorticity on lifespan of smooth solutions.
