A simple approach to functional inequalities for non-local Dirichlet forms

Jian Wang (2014)

ESAIM: Probability and Statistics

With direct and simple proofs, we establish Poincaré type inequalities (including Poincaré inequalities, weak Poincaré inequalities and super Poincaré inequalities), entropy inequalities and Beckner-type inequalities for non-local Dirichlet forms. The proofs are efficient for non-local Dirichlet forms with general jump kernel, and also work for Lp(p> 1) settings. Our results yield a new sufficient condition for fractional Poincaré inequalities, which were recently studied in [P.T. Gressman,...

A simple formula for an analogue of conditional Wiener integrals and its applications. II

Dong Hyun Cho (2009)

Czechoslovak Mathematical Journal

Let C [ 0 , T ] denote the space of real-valued continuous functions on the interval [ 0 , T ] with an analogue w ϕ of Wiener measure and for a partition 0 = t 0 < t 1 < < t n < t n + 1 = T of [ 0 , T ] , let X n C [ 0 , T ] n + 1 and X n + 1 C [ 0 , T ] n + 2 be given by X n ( x ) = ( x ( t 0 ) , x ( t 1 ) , , x ( t n ) ) and X n + 1 ( x ) = ( x ( t 0 ) , x ( t 1 ) , , x ( t n + 1 ) ) , respectively. In this paper, using a simple formula for the conditional w ϕ -integral of functions on C [ 0 , T ] with the conditioning function X n + 1 , we derive a simple formula for the conditional w ϕ -integral of the functions with the conditioning function X n . As applications of the formula with the function X n , we evaluate the conditional w ϕ -integral...

A simple proof of Fishburn's moments theorem.

María Lina Martínez García (1985)

Trabajos de Estadística e Investigación Operativa

We derive a necessary condition for stochastic dominance of any order based on the Laplace transform of probability measures on [0,∞) for which it follows easily Fishburn's theorem on the lexicographic order of the moments.
