Sharp Large Deviations for Gaussian Quadratic Forms with Applications

Under regularity assumptions, we establish a sharp large deviation principle for Hermitian quadratic forms of stationary Gaussian processes. Our result is similar to the well-known Bahadur-Rao theorem [2] on the sample mean. We also provide several examples of application such as the sharp large deviation properties of the Neyman-Pearson likelihood ratio test, of the sum of squares, of the Yule...

Courbes modulaires et 11-rang de corps quadratiques

TABLE DES MATI`ERES Introduction 1. Structure galoisienne de courbes modulaires 2. Le cas p = 23 3. Méthode et Résultats Remerciements Bibliographie Nous construisons 53 corps quadratiques imaginaires ayant un 11-rangégaì a 3, et sept corps quadratiques réels de 11-rangégaì a 2. Ce sont, ` a notre connaissance, les premiers exemples de tels corps. We construct 53 imaginary quadratic fields of 1...

Girsanov and Feynman-kac Type Transformations for Symmetric Markov Processes

– Studied in this paper is the transformation of an arbitrary symmetric Markov process X by multiplicative functionals which are the exponential of continuous additive functionals of X having zero quadratic variations. We characterize the transformed semigroups by their associated quadratic forms. This is done by first identifying the symmetric Markov process under Girsanov transform, which may...
