在这项工作中,我们考虑的随机柯西问题驱动的规范$alpha$-稳定的圆柱Levy过程。这种噪声自然地概括了圆柱布朗运动或时空高斯白色噪声。我们得到了随机柯西问题弱解和温和解存在的一个充分必要条件,并建立了解的时间不规则性。
In this work, we consider the stochastic Cauchy problem driven by the canonical $alpha$-stable cylindrical Levy process. This noise naturally generalises the cylindrical Brownian motion or space-time Gaussian white noise. We derive a sufficient and necessary condition for the existence of the weak and mild solution of the stochastic Cauchy problem and establish the temporal irregularity of the solution.
