Abstract
Tempered operator stable laws are operator stable laws without normal component, for which we modify their Levy measure to reduce the expected number of large jumps. We will introduce a characterisation of the obtained Levy measure. Tempered operator stable distributions may have all moments finite. We prove short and long time behavior of the tempered operator stable Levy process: In a short time frame it is close to an operator stable process while in a long time frame it approximates a Brownian motion.
Then we construct a random walk, which converges in distribution to a random vector with a tempered operator stable distribution under a triangular array scheme. We show that the random walk process converges to the Levy process generated by the tempered operator stable distribution in the sense of finite-dimensional distributions.
We find probabilistic representations of tempered operator stable Levy process. Such representation can be used for simulation.
