Title

On L_2-small deviations of Slepian process

AMS Subj-class

Keywords

Abstract

    The exact L_2-small deviation asymptotics is studied for the Slepian process S(t) = W(t+a) - W(t), t\in[0,1], where W(t) is Brownian motion, for the parameter value a= 1/3. The result is based on Karhunen–Loève expansion which reduces the original problem to the study of a matrix Sturm-Liouville problem. Asymptotics is derived using Wenbo Li’s comparison theorem together with complex analysis methods.
