算子自相似随机场的指数

Exponents of operator self-similar random fields

Gustavo Didier, Mark M. Meerschaert, Vladas Pipiras

摘要:

如果X(c^E t)和c^HX(t)对于某些线性算子E和H具有相同的有限维分布,我们说随机向量场X(t)是算子自相似的.由于对称性,指数E和H通常不是唯一的。本文刻画了给定Domain指数的可能的值域指数集H,反之刻画了给定Domain指数的可能的值域指数集E。

英文摘要:

If X(c^E t) and c^H X(t) have the same finite-dimensional distributions for some linear operators E and H, we say that the random vector field X(t) is operator self-similar. The exponents E and H are not unique in general, due to symmetry. This paper characterizes the possible set of range exponents H for a given domain exponent, and conversely, the set of domain exponents E for a given range exponent.
