【 摘 要 】

We investigate the large deviation behaviour of a point process sequence based on a stationary symmetric alpha-stable (0 < alpha < 2) discrete-parameter random field using the framework of Hult and Samorodnitsky (2010). Depending on the ergodic theoretic and group theoretic structures of the underlying nonsingular group action, we observe different large deviation behaviours of this point process sequence. We use our results to study the large deviations of various functionals (e.g., partial sum, maxima, etc.) of stationary symmetric stable fields. (C) 2015 Elsevier B.V. All rights reserved.
