Abstract: This article concerns a class of Ornstein-Uhlenbeck type Markov processes and for which the level sets will be approached. By constructing a new class f processes,we shall obtain an inequality on the Hausdorff dimensions of the level sets for the Ornstein-Uhlenbeck type Markov processes. Based on this result, we finally verify that any two independent O-U.M.P with α-stable processes could collide with probability one.

Key words: α-stable process, Ornstein-Uhlenbeck type Markov process, Range, Hausdorff dimension, collision
