柱面稳态噪声驱动的随机发展方程

Stochastic evolution equations driven by cylindrical stable noise

Tomasz Kosmala, Markus Riedle

摘要:

证明了由定义在希尔伯特空间上的标准$α$ -稳定圆柱Lévy过程驱动的随机发展方程的温和解的存在唯一性。假设系数在方程中存在的生成器的分数幂的某些域之间映射。该解决方案被构造为一个弱极限的皮卡德迭代使用紧密性参数。利用Yamada-Watanabe定理的一般形式得到了该方程的强解的存在性.

英文摘要:

We prove existence and uniqueness of a mild solution of a stochastic evolution equation driven by a standard $α$-stable cylindrical Lévy process defined on a Hilbert space for $α\in (1,2)$. The coefficients are assumed to map between certain domains of fractional powers of the generator present in the equation. The solution is constructed as a weak limit of the Picard iteration using tightness arguments. Existence of strong solution is obtained by a general version of the Yamada--Watanabe theorem.
