    Comparison results for the lower tail of Gaussian seminorms (1992)
    Springer
    Journal of theoretical probability 5 (1992), S. 1-31 
    Details
    ISSN: 1572-9230
    Keywords: Lower tail ; Gaussian seminorms ; Gaussian processes ; infinite dimensional Brownian motion
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mathematics
    Notes: Abstract Let ξ=(ξ n ) be i.i.d.N(0, 1) random variables andq(x), q′(x):R ∞→[0, ∞) be seminorms. We investigate necessary and sufficient conditions that the ratio ofP(q(ξ)〈ε) andP(q′(ξ)〈ε) goes to a positive constant as ε→0+. We give satisfactory answers forl 2-norms and also some results for sup-norms andl p-norms. Some applications are given to the rate of escape of infinite dimensional Brownian motion, and we give the lower tail of the Ornstein-Uhlenbeck process and a weighted Brownian bridge under theL 2-norms.

    Small Deviations for Gaussian Markov Processes Under the Sup-Norm (1999)
    Springer
    Journal of theoretical probability 12 (1999), S. 971-984

    ISSN: 1572-9230
    Keywords: Small ball problem ; Gaussian Markov processes ; Brownian motion ; weighted norms
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mathematics
    Notes: Abstract Let {X(t); 0≤t≤1} be a real-valued continuous Gaussian Markov process with mean zero and covariance σ(s, t) = EX(s) X(t) ≠ 0 for 0〈s, t〈1. It is known that we can write σ(s, t) = G(min(s, t)) H(max(s, t)) with G〉0, H〉0 and G/H nondecreasing on the interval (0, 1). We show that $$\mathop {\lim }\limits_{\varepsilon \to 0} \varepsilon ^2 \log P({\text{ }}\mathop {\sup }\limits_{0 〈 t \leqslant 1} {\text{ |}}X(t)| 〈 \varepsilon ) = - (\pi ^2 /8)\int_0^1 {(G'H - H'G)dt} $$ In the critical case, i.e. this integral is infinite, we provide the correct rate (up to a constant) for log P(sup0〈t≤1 |X(t)|〈∈) as ∈→0 under regularity conditions.

    Small Ball Estimates for Gaussian Processes under Sobolev Type Norms (1999)
    Springer
    Journal of theoretical probability 12 (1999), S. 699-720 
    Details
    ISSN: 1572-9230
    Keywords: Gaussian process ; Wiener process ; fractional Brownian motion ; Sobolev norm ; Chung's LIL
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mathematics
    Notes: Abstract A sharp small ball estimate under Sobolev type norms is obtained for certain Gaussian processes in general and for fractional Brownian motions in particular. New method using the techniques in large deviation theory is developed for small ball estimates. As an application the Chung's LIL for fractional Brownian motions is given in this setting.

    Notes: Summary Let (X(t), t∈S) be a real-valued stochastic process with ℙ(X(0)=0)=1 and $$\mathbb{P} (\mathop {\lim }\limits_{t \to \infty } X(t) = \infty ) = 1$$ . In this paper we are interested in the reluctance of such a process to tend to infinity. This entails determining the rate of escape of the associated process $$(\mathop {\inf }\limits_{s\underset{\raise0.3em\hbox{$\smash{\scriptscriptstyle-}$}}{ \geqslant } t} X(s), t \in S)$$ , the so-calledfuture infima process.

    Notes: Summary Let μ be a centered Gaussian measure on a Hilbert spaceH and let $$B_R \subseteq H$$ be the centered ball of radiusR〉0. Fora∈H and $$\mathop {\lim }\limits_{t{\mathbf{ }} \to {\mathbf{ }}\infty } {\mathbf{ }}R(t)/t〈 {\mathbf{ }}||a||$$ , we give the exact asymptotics of μ(B R(t)+t·a) ast→∞. Also, upper and lower bounds are given when μ is defined on an arbitrary separable Banach space. Our results range from small deviation estimates to large deviation estimates.
