Small Ball Estimates for Quasi-norms
نویسندگان
چکیده
This note contains two types of small ball estimates for random vectors in finite dimensional spaces equipped with a quasi-norm. In the first part, we obtain bounds for the small ball probability of random vectors under some smoothness assumptions on their density function. In the second part, we obtain Littlewood-Offord type estimates for quasi-norms. This generalizes a result which was previously obtained in [FS07, RV09].

Small ball estimates for Brownian motion and the Brownian sheet
Small ball estimates for Brownian motion and the Brownian sheet are obtained when the balls are given by certain H61der norms. As an application, we establish some lira inf results for Gaussian samples of these processes, as well as Chung's LIL in this setting, but now we introduce some notation. Let I = [0, 1 ], with Co(I) the continuous real-valued function f ( . ) on I such that f ( 0 ) = 0....
متن کاملNorms and Spectral Radii of Linear Fractional Composition Operators on the Ball
We give a new proof that every linear fractional map of the unit ball induces a bounded composition operator on the standard scale of Hilbert function spaces on the ball, and obtain norm bounds analogous to the standard one-variable estimates. We also show that Cowen’s one-variable spectral radius formula extends to these operators. The key observation underlying these results is that every lin...
متن کاملISS in Different Norms for 1-D Parabolic PDES With Boundary Disturbances
For 1-D parabolic PDEs with disturbances at both boundaries and distributed disturbances we provide ISS estimates in various norms. Due to the lack of an ISS Lyapunov functional for boundary disturbances, the proof methodology uses (i) an eigenfunction expansion of the solution, and (ii) a finite-difference scheme. The ISS estimate for the sup-norm leads to a refinement of the well-known maximu...
متن کاملNon-degeneracy of Sobolev Pseudo-norms of fractional Brownian motion
Applying an upper bound estimate for small L2 ball probability for fractional Brownian motion (fBm), we prove the non-degeneracy of Sobolev pseudo-norms of fBm.
متن کاملSOME REMARKS ON WEAKLY INVERTIBLE FUNCTIONS IN THE UNIT BALL AND POLYDISK
We will present an approach to deal with a problem of existence of (not) weakly invertible functions in various spaces of analytic functions in the unit ball and polydisk based on estimates for integral operators acting between functional classes of different dimensions.
