利用白色噪声分布的坐标变换,构造了以任意真实的数为特征值的L evy Laplacian的特征函数.在这类特征函数的直接积分Hilbert空间上对角化L evy-Laplacian算子,得到相应的等连续半群.此外,从一维稳定过程出发,构造了一个与L evy Laplacian相关的无穷维随机过程.
Eigenfunctions of the L evy Laplacian with an arbitrary real number as an eigenvalue are constructed by means of a coordinate change of white noise distributions. The L evy Laplacian is diagonalized on the direct integral Hilbert space of such eigenfunctions and the corresponding equi-continuous semigroup is obtained. Moreover, an innite dimensional stochastic process related to the L evy Laplacian is constructed from a onedimensional stable process.
