Mb. Marcus et K. Shen, BOUNDS FOR THE EXPECTED NUMBER OF LEVEL-CROSSINGS OF CERTAIN HARMONIZABLE INFINITELY DIVISIBLE PROCESSES, Stochastic processes and their applications, 76(1), 1998, pp. 1-32
Let ENu(0, 1) denote the expected number of crossings of a level u, in
a fixed time interval [0,1], by a large class of real valued symmetri
c stationary harmonizable infintely divisible processes which includes
stationary harmonizable stable processes. Equivalent upper and lower
bounds are given for EN0(0, 1) and a precise asymptotic limit is given
for ENu(0, 1), as u --> (infinity). (C) 1998 Published by Elsevier Sc
