Uniform bounds on symbolic powers

open access: yesJournal of Algebra, 2013
Let \(R\) be a commutative Noetherian ring with \(1\). Let \(I\) be an ideal of \(R\) and let \(S=R\backslash \cup P_{i}\) where \(P_{i}\) ranges over associated primes of \(I.\) Then the \(nth\) symbolic power of \(I\) is the ideal \( I^{(n)}=I^{n}R_{S}\cap R.\) Thus for a prime ideal \(P\) we have \( P^{(n)}=P^{n}R_{P}\cap R.\) Obviously \(I^{n ...

Direction-of-Arrival Estimation Based on Variational Bayesian Inference Under Model Errors

open access: yesRemote Sensing
The current self-calibration approaches based on sparse Bayesian learning (SBL) demonstrate robust performance under uniform white noise conditions. However, their efficacy degrades significantly in non-uniform noise environments due to acute sensitivity

A Note on the Separability Principle in Economies with Single-Peaked [PDF]

open access: yes
We consider the problem of allocating an infinitely divisible commodity among a group of agents with single-peaked preferences. A rule that has played a central role in the analysis of the problem is the so-called uniform rule.

Uniform bounds in noetherian rings

open access: yesInventiones Mathematicae, 1992
The author is interested in various types of uniform behavior for commutative Noetherian rings. This is probably best illustrated by just quoting his two main results. \textit{Uniform Artin-Rees}: Let \(S\) be a Noetherian ring. Let \(N\leq M\) be two finitely generated \(S\)-modules.

Strongly uniform bounds from semi-constructive proofs

open access: yesAnnals of Pure and Applied Logic, 2004
In 2003, the second author obtained metatheorems for the extraction of effective (uniform) bounds from classical, prima facie non-constructive proofs in functional analysis. These metatheorems for the first time cover general classes of structures like arbitrary metric, hyperbolic, CAT(0) and normed linear spaces and guarantee the independence of the ...

Monotonicity and bounds on Bessel functions

open access: yesElectronic Journal of Differential Equations, 2000
survey my recent results on monotonicity with respect to order of general Bessel functions, which follow from a new identity and lead to best possible uniform bounds.

Guessing with a Bit of Help

open access: yesEntropy, 2019
What is the value of just a few bits to a guesser? We study this problem in a setup where Alice wishes to guess an independent and identically distributed (i.i.d.) random vector and can procure a fixed number of k information bits from Bob, who has ...

Universal Heisenberg uncertainty relations for all massless particles

open access: yesNew Journal of Physics
We derive the uncertainty relations between position and momentum (or wavector) in a uniform way for all massless particles. As expected, the lower bound $\gamma_{\textrm{min}} = (1+\sqrt{1/4+2 h})$ in the uncertainty relation grows with the particle’s ...

Plastyczne Wyczerpanie Nośności Ustrojów Płytowo-Żebrowych. Cz. 2. Rozwiązania Statyczne.

open access: yesEngineering Transactions, 1963
This is the second part of a work of which the first part appeared in Rozprawy Inzynierskie, where the problem of exhaustion of the load carrying capacity of a bent ribbed plate structures was analysed for a kinematically admissible field of strain ...

Positive Periodic Solution for Second-Order Singular Semipositone Differential Equations

open access: yesAbstract and Applied Analysis, 2013
We study the existence of a positive periodic solution for second-order singular semipositone differential equation by a nonlinear alternative principle of Leray-Schauder.
