Chevet type inequality and norms of submatrices
We prove a Chevet type inequality which gives an upper bound for the norm of an isotropic log-concave unconditional random matrix in terms of expectation of the supremum of “symmetric exponential” processes compared to the Gaussian ones in the Chevet inequality. This is used to give sharp upper estimate for a quantity Γk,m that controls uniformly the Euclidean operator norm of the sub-matrices ...
متن کاملNorms of random submatrices and sparse approximation
Many problems in the theory of sparse approximation require bounds on operator norms of a random submatrix drawn from a fixed matrix. The purpose of this note is to collect estimates for several different norms that are most important in the analysis of `1 minimization algorithms. Several of these bounds have not appeared in detail. Résumé Sur la norme de sous-matrice tirée aléatoirement. Beauc...

Norms of Inequality
This paper investigates the linkage between social norms and wage dispersion between many industrialised countries. It examines social perceptions to legitimate differences between high and low paid occupations, and uses regression analysis to attribute causes for such differing social structures. The paper concludes that there exists a relationship between levels of inequality and the social s...
متن کاملInequality for p-norms of positive matrices
This paper derives an inequality relating the p-norm of a positive 2×2 block matrix to the p-norm of the 2×2 matrix obtained by replacing each block by its p-norm. The inequality had been known for integer values of p, so the main contribution here is the extension to all values p ≥ 1. In a special case the result reproduces Hanner’s inequality. As an application in quantum information theory, ...
