Comparison results for the lower tail of Gaussian seminorms

WV Li - Journal of Theoretical Probability, 1992 - Springer
Let ξ=(ξ n ) be iidN(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 …
