On Global Attractors for a Class of Parabolic Problems
(Natural Sciences Publishing Corp-nsp, 2014-03-01)
This paper is devoted to study the existence of global attractor in H-0(1)(Omega) and uniform bounds of it in L-infinity(Omega) for a class of parabolic problems with homogeneous boundary conditions wich involves a uniform ...

This paper is devoted to study the existence of global attractor in H0 1 (Ω) and uniform bounds of it in L∞(Ω) for a class of parabolic problems with homogeneous boundary conditions wich involves a uniform strongly elliptic ...
Uniform sparse bounds for discrete quadratic phase Hilbert transforms
(2017-09)
Consider the discrete quadratic phase Hilbert Transform acting on $\ell^{2}(\mathbb{Z})$ finitely supported
functions
$$
H^{\alpha} f(n) : = \sum_{m \neq 0} \frac{e^{i\alpha m^2} f(n - m)}{m}.
$$
We prove that, ...

Unitarization of uniformly bounded subgroups in finite von Neumann algebras
(Oxford University Press, 2014-12)
This note presents a new proof of the fact that every uniformly bounded group of invertible elements in a finite von Neumann algebra is similar to a unitary group. In 1974, Vasilescu and Zsido proved this result using the ...
Bounds on functionals of the distribution treatment effects
(2010-06-01)
Bounds on the distribution function of the sum of two random variables with known marginal distributions obtained by Makarov (1981) can be used to bound the cumulative distribution function (c.d.f.) of individual treatment ...
A counterexample for H ∞ approximable functions
(American Mathematical Society, 2000-12)
Let D be the unit disk. We show that for some relatively closed set F ⊂ D there is a function f that can be uniformly approximated on F by functions of H∞, but such that f cannot be written as f = h + g, with h ∈ H∞ and g ...
A Sharp Uniform Bound for the Distribution of Sums of Bernoulli Trials
(Cambridge Univ. Press., 2016)
In this note we establish a uniform bound for the distribution of a sum S-n = X-1 + ... + X-n of independent non-homogeneous Bernoulli trials. Specifically, we prove that sigma P-n(S-n = j) <= eta, where sigma(n) denotes ...
