摘要 研究了N维空间中带阻尼项的欧拉-泊松方程组的径向对称解的爆破.当方程组非奇异的经典解(ρ,u)在[0,R]上有紧支集(R>0是正常数),且初始速度u满足一定的初值条件,借助积分法,其径向对称解会在有限时间内爆破. The paper discusses the blowup problem for Euler-Poisson equations with damping in RN.By the integra-tion method,under certain initial condition for initial velocity u,the non-trivial classical solutions (ρ,u) with com-pact support in[0,R],where R>0 is a positive constant,can blow up in the finite time.
