摘要
Multivariate random fields whose distributions are invariant under operator-scalings in both the time domain and the state space are studied. Such random fields are called operator-self-similar random fields and their scaling operators are characterized. Two classes of operator-self-similar stable random fields X = {X (t), t is an element of R-d} with values in R-m are constructed by utilizing homogeneous functions and stochastic integral representations.
